Answer: No

Explanation:

A non-renewable resource is the one which cannot be replenish when once used. They are expected to short out of supply because of the fact that with the increasing population worldwide the demand for the resources will also increase. As a result of this the population may face scarcity of resources in future. Such resources cannot be expected to be used sustainably as they get completely used up in a single use. For example fossil fuels like coal, petroleum and natural gas.

No, the nonrenewable resources can be used sustainably because the nonrenewable resources are the limited.

The renewable resources the resources which are naturally replenish themselves and the  nonrenewable resources will not replenish. The  nonrenewable resources are have limit in the supply and which cannot be used sustainably. The not all the renewable energy is the sustainable energy.

Answer:

1.325 x 10²⁴ Co atoms

Explanation:

1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up elements of molecules making up a compound.

Therefore 1 mol of the element cobalt is made of 6.022 x 10²³ atoms of Co

so if 1 mol of Co contains - 6.022 x 10²³ atoms of Co

then 2.2 mol of Co contains - 6.022 x 10²³ /mol x 2.2 mol

number of Co atoms in 2.2 mol of Co is - 1.325 x 10²⁴ Co atoms

Answer:

The volume would be 800mL and it shows that it is constant.

Explanation:

Given parameters:

Intial volume of gas V₁ = 800mL

Initial temperature T₁ = -23°C to Kelvin; we use K = °C + 273 = -23 + 273 =                                                          250K

Inital pressure P₁ = 300torr

Final temperature T₂ = 227°C to K = 227 + 273 = 500K

Final pressure P₂ = 600torr

Unknown parameter:

Final volume V₂ = ?

To solve this problem, we use the General gas law or the combined gas law where we assume that n=1, this gives:

             [tex]\frac{P_{1} V_{1} }{T_{1} }[/tex] =   [tex]\frac{P_{2} V_{2} }{T_{2} }[/tex]

Since the unknown is V₂, we make it the subject of the formula:

                V₂ = [tex]\frac{P_{1} V_{1} T_{2} }{P_{2} T_{1} }[/tex]

                V₂ = [tex]\frac{300x800x500}{600x250}[/tex]

                V₂ = 800mL

After the temperature and pressure changes the final volume of the gas is calculated to be approximately 800.05 mL.

To find the final volume of a gas when given changes in temperature and pressure, we use the combined gas law:

(P₁ * V₁)/T₁ = (P₂ * V₂)/T₂

Here, the variables represent:

The initial conditions given are:

First, convert the temperatures to Kelvin:

T = -23.0 + 273.15 = 250.15 K

T₂ = 227.0 + 273.15 = 500.15 K

Next, apply the combined gas law to find V₂:

(300.0 torr * 800.0 mL) / 250.15 K = (600.0 torr * V₂) / 500.15 K

Solving for V₂:

[tex]V_2 &= \left( \frac{(300.0 \, \text{torr}) \times (800.0 \, \text{mL})}{250.15 \, \text{K}} \right) \times \frac{500.15 \, \text{K}}{600.0 \, \text{torr}} \\\\V_2 &= \left( \frac{240000 \, \text{torr} \cdot \text{mL}}{250.15 \, \text{K}} \right) \times \frac{500.15 \, \text{K}}{600.0 \, \text{torr}} \\\\V_2 &= \left( \frac{240000}{250.15} \right) \times \frac{500.15}{600.0} \\\\V_2 &= 959.90 \times 0.83358 \\\\V_2 &\approx 800.05 \, \text{mL}[/tex]

Therefore, the final volume of the gas is approximately 800.05 mL.

Answer:

1.12dm³

Explanation:

The reaction is a decompositon reaction. It is expressed below:

Mg(HCO₃)₂ + Heat → MgCO₃ + H₂O + CO₂

This is the balanced reaction equation.

We have 1 mole of Mg, 2 mole of H, 2 mole of C, 6 mole of O on both sides of the reaction.

To calculate the volume of CO₂ gas evolved at S.T.P:

We work from the known to the unknown.

The known is Mg(HCO₃)₂ and the unknown is CO₂

1. Find the number of moles of Mg(HCO₃)₂ from the given mass

2. Since we know that chemical reactions obey the law of conservation of mass. The balanced chemical reaction shows that, 1 mole of Mg(HCO₃)₂ would give 1 mole of CO₂

3. We use information from (2) to find the number of moles of CO₂. With the number of moles of CO₂ found, we use the formula below to find the volume evolved at S.T.P

Volume evolved =

number of moles of CO₂ x 22.4dm³mol⁻¹

Solution:

Given/known parameters:

Mass of Mg(HCO₃)₂ = 7.3g

Step 1:

Number of moles

of Mg(HCO₃)₂ = mass/molar mass

Molar mass of Mg(HCO₃)₂ :

Atomic mass of Mg = 24gmol⁻¹

H = 1gmol⁻¹

C = 12gmol⁻¹

O = 16gmol⁻¹

Molar Mass Mg(HCO₃)₂

= [24 + 2{1 + 12 + (16 x3)} ]

= 24 + 2(1 +12 + 48)

= 24 + 122

= 146gmol⁻¹

Number of moles of

Mg(HCO₃)₂ = 7.3g/126gmol⁻¹ = 0.05mol

Step 2:

We know from the balanced equation that:

1mole of Mg(HCO₃)₂ = 1 mole of CO₂

So: 0.05mol of Mg(HCO₃)₂ = ?

This would also produce 0.05mol of CO₂

Step 3:

Volume of CO₂ evolved =

number of moles of CO₂ x 22.4dm³mol⁻¹

= 0.05 x 22.4

= 1.12dm³

The volume of CO₂ gas evolved at S. T. P is 1.12dm³

The volume of carbon dioxide gas evolved at STP by heating 7.3 gram of Mg(HCO3)2 will be 1.12 L or 1120 ml

The reaction is a decomposition reaction;

From the reaction

1 mole of Mg(HCO₃)₂ produces 1 mole of CO₂ after decomposition.

Therefore, to determine the volume of CO₂ produced by 7.3 grams of Mg(HCO₃)₂

Number of moles = Mass/relative formula mass

RFM of Mg(HCO₃)₂  =146.33868 g/mol

Therefor;

Number of moles = 7.3 g/146.33868 g/mol

                             = 0.04988

                             = 0.05 moles

From the equation;

1 mole of Mg(HCO₃)₂ produces 1 mole of CO₂ after decomposition.

Therefore;

Moles of carbon dioxide produced is 0.05 moles

From molar gas volume;

1 mole of  CO₂  at STP occupies 22.4 L

Thus;

0.05 moles will occupy;

= 0.05 × 22.4 L

= 1.12 L or 1120 mL

Therefore; volume of carbon dioxide gas evolved at STP by heating 7.3 gram of Mg(Hco3)2 will be​ 1.12 L or 1120 ml

To find the number of phosphorus atoms in 4.90 mol of copper(II) phosphate, first calculate the number of moles of phosphorus atoms in copper(II) phosphate follow by using Avogadro's number to convert moles to atoms. The total number of phosphorus atoms in 4.90 mol of copper(II) phosphate is 5.90 x 10²⁴ atoms.

Explanation:

To find the number of phosphorus atoms in 4.90 mol of copper(II) phosphate, first calculate the number of moles of phosphorus atoms in copper(II) phosphate: 2 mol of phosphorus atoms per 1 mol of Cu₃(PO₄)₂. So, 4.90 mol of Cu₃(PO₄)₂ would contain 2 * 4.90 = 9.80 mol of phosphorus atoms. Then, use Avogadro's number to convert moles to atoms: 9.80 mol * 6.022 x 10²³ atoms/mol = 5.90 x 10²⁴ atoms of phosphorus.

I. Changing the pressure:

II. Changing the temperature:

III. Changing the H₂ concentration:

Explanation:

Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

I. Changing the pressure:

For the reaction: CH₄(g) + 2H₂S(g) ⇄ CS₂(g) + 4H₂(g),

The reactants side (left) has 3.0 moles of gases and the products side (right) has 5.0 moles of gases.

II. Changing the temperature  

The reaction is endothermic since the sign of ΔH is positive.

CH₄(g) + 2H₂S(g) + heat ⇄ CS₂(g) + 4H₂(g).

The T is a part of the reactants, increasing the T increases the amount of the reactants. So, the reaction will be shifted to the right to suppress the effect of increasing T and the amount of H₂S(g) will decrease.

The T is a part of the reactants, increasing the T decreases the amount of the reactants. So, the reaction will be shifted to the left to suppress the effect of decreasing T and the amount of H₂S(g) will increase.

III. Changing the H₂ concentration:

H₂ is a part of the products.

H₂ is a part of the products, increasing H₂ increases the amount of the products. So, the reaction will be shifted to the left to suppress the effect of increasing H₂ and the amount of H₂S(g) will increase.

H₂ is a part of the products, decreasing H₂ decreases the amount of the products. So, the reaction will be shifted to the right to suppress the effect of decreasing H₂ and the amount of H₂S(g) will decrease.

Explanation:

Answer:

1. 6.45 L

2. 1.76 x 10²³ molecules

Explanation:

1. Avagadros law states that volume of gas at constant temperature and pressure is directly proportional to the amount / number of moles of that gas

we can use the following equation

v1/n1 = v2/n2

where v1 is volume and n1 is number of moles at first instance

and v2 is volume and n2 is number of moles at second instance

at the first instance - n1 = 0.218 mol

second instance - n2  = 0.218 mol + 0.075 mol  = 0.293 mol

substituting the values

4.8 L / 0.218 mol = v2 / 0.293 mol

v2 = 6.45 L

new volume is 6.45 L

2. 1 mol of any substance is made of 6.022 x 10²³ units. These units could be atoms making up elements or molecules making up a compound.

therefore if 1 mol consists of 6.022 x 10²³  molecules

then 0.293 mol consists of - 6.022 x 10²³ molecules/mol x 0.293 mol = 1.76 x 10²³ molecules

therefore there are 1.76 x 10²³ molecules now in the cylinder

The molecule Br2 is a diatomic molecule made up of two bromine atoms, which exists as a liquid at room temperature due to its size and number of electrons.

The molecule Br2, which stands for Bromine molecule consists of two bromine atoms. This molecule is unique in that it is one of the few elements that exist as a liquid at room temperature.

The bromine molecule, Br2, is a simple diatomic molecule with a single, covalent bond holding the two bromine atoms together. Due to its size and number of electrons, Br2 is heavier than many other diatomic molecules, which is why it exists as a liquid at room temperature while other diatomic molecules like O2 and N2 are gases.

This specific behavior plays a significant role in understanding the trend of molecular states. For instance, Bromine's state as a liquid at room temperature, as opposed to I2 (a solid) and Cl2 (a gas) informs us about the impact of the physical state on a molecule's entropy.

Bonds are broken and new bonds are formed during chemical reactions only.

Explanation:

So, the right choice is:

Bonds are broken and new bonds are formed during chemical reactions only.

Final answer:

Bonds are broken and new bonds are formed during chemical reactions only, not during physical changes. A chemical reaction reorganizes atoms into new substances, which involves breaking old bonds and forming new ones, fundamentally changing the composition of the reactants.

Explanation:

The true statement is that bonds are broken and new bonds are formed during chemical reactions only. During a chemical reaction, reactants undergo a transformation where their chemical bonds are broken, atoms are rearranged, and new substances with new bonds are formed, called products. This process involves energy changes, where breaking bonds requires an input of energy while forming bonds releases energy.

Conversely, physical changes involve a change in the form or physical properties of a substance, without altering the chemical composition or the bonds within molecules. Thus during chemical reactions, old bonds are broken, and new bonds form to create new substances with different chemical and physical properties; this is essential in defining a chemical change. Physical changes, on the other hand, do not involve changes in the bonds that hold atoms together within a molecule.

A nuclear reaction is at its most basic nothing more than a reaction process that occurs in an atomic nucleus. They typically take place when a nucleus of an atom gets smacked by either a subatomic particle (usually a "free neutron," a short-lived neutron not bound to an existing nucleus) or another nucleus

but alot of things happen to be honest to much to put down but the basic is a blast of energy that is super heated by friction that is followd by nuclear after fall and this can be very deadly even miles away

hope this helps

Final answer:

In a nuclear reaction, the nucleus of an atom undergoes a change, often transforming into a different element or isotope and releasing tremendous amounts of energy. This energy, derived from the nuclear binding energy, is much greater than energy changes in chemical reactions.

Explanation:

A nuclear reaction is a process where the nucleus of an atom changes. This change can result in the transformation of elements through a process known as transmutation or the conversion of atoms into various isotopes. Unlike chemical reactions, where electrons are transferred or shared between atoms, nuclear reactions involve changes in the nucleus and typically release far greater amounts of energy. This energy comes from the nuclear binding energy, which binds protons and neutrons in the nucleus.

Two primary types of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In decay reactions, an unstable nucleus emits radiation to form a more stable nucleus, while transmutation reactions occur when nuclei or subatomic particles collide and transform into a different element or isotope. These processes often produce energy orders of magnitude greater than that produced by chemical reactions, highlighting the immense power of nuclear changes.

Answer:

IO₂

Explanation:

We have been given the mass percentages of the elements that makes up the compound:

Mass percentage given are:

Iodine = 79.86%

Oxygen = 20.14%

To calculate the empirical formula which is the simplest formula of the compound, we follow these steps:

> Express the mass percentages as the mass of the elements of the compound.

> Find the number of moles by dividing through by the atomic masses

> Divide by the smallest and either approximate to nearest whole number or multiply through by a factor.

> The ratio is the empirical formula of the compound.

Solution:

I O

% of elements 79.86 20.14

Mass (in g) 79.86 20.14

Moles(divide by

Atomic mass) 79.86/127 20.14/16

Moles 0.634 1.259

Dividing by

Smallest 0.634/0.634 1.259/0.634

1 2

The empirical formula is IO₂

To find the empirical formula of a compound, we calculate the moles of each element using their atomic masses. Dividing the moles by the smallest value gives us the ratio of the elements, which represents the empirical formula. For the compound containing 79.86% iodine and 20.14% oxygen, the empirical formula is IO2.

To find the empirical formula, we need to determine the simplest whole-number ratio between the elements in the compound. To do this, we first assume we have 100g of the compound, which allows us to convert the percentages to grams. We can then calculate the moles of each element using their atomic masses. The ratio of moles gives us the empirical formula.

For the given compound that contains 79.86% iodine and 20.14% oxygen by mass:

Assuming 100g of the compound, we have 79.86g of iodine and 20.14g of oxygen. The moles of iodine can be calculated using its atomic mass (126.9 g/mol), which gives us 0.628 moles. The moles of oxygen can be calculated using its atomic mass (16.0 g/mol), which gives us 1.259 moles. Dividing both moles by the smaller value (0.628 moles) gives us the ratio of 1:2. Therefore, the empirical formula for the compound is IO2.

TLDR: A.

Understanding the idea of chemical equations is sometimes a hard concept to grasp in general chemistry because it’s typically not explained well. What a chemical equation represents is what literally happens on the subatomic level. The coefficients in front of the reactants and products mean, number for number, what you would get if you performed the reaction. It’s like an atomic recipe - you can only “make” things when you have enough ingredients. When an ingredient runs out, you can’t produce any products anymore. The ingredient that runs out the quickest is known as the “limiting reagent”, as it literally limits what you can produce.

In the equation above, 2 equivalents of “a” and 3 equivalents of “b” are consumed to produce the products. This means that “b” gets consumed faster than “a”. To make one sample of products, you need two molecules of “a” and three molecules of “b”. If you start out with four moles of each reactant (the same number of atoms), you’ll run out of “b” before “a” because the reaction consumes more molecules of “b” than molecules of “a”. Therefore, the answer would be A. You would need 6 moles of “b” to finish the reaction and use up the remaining “a” (a 2:3 ratio, just like in the balanced equation).

Hope this helps!

Final answer:

The limiting reactant is determined by dividing the moles of each reactant by its stoichiometric coefficient. Reactant 'B' is limiting because it gives a smaller ratio compared to 'A' after the division, indicating that it will be consumed first.

Explanation:

Identifying the Limiting Reactant

To determine the limiting reactant, you must first understand the stoichiometric relationship between reactants in a balanced chemical equation. In the given equation 2a+3b → c, the stoichiometry indicates that 2 moles of a react with 3 moles of b to produce c. We have 4.0 moles of both a and b. To find the limiting reactant, divide the number of moles of each reactant by its respective coefficient:

For a: 4.0 moles ÷ 2 = 2

For b: 4.0 moles ÷ 3 = 1.33

Reactant b will run out first because it produces a smaller ratio (1.33) compared to reactant a (2) when divided by their coefficients. Therefore, b is the limiting reactant, and the correct answer is 'A) B is limiting because 4.0 mol and 6.0 mol are needed'.

Explanation:

The equation of the reaction is given as:

                  2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

Given parameters:

Number of moles of acetylene = 35.0mol

Number of moles of oxygen in the tank = 84.0mol

Unknown:

Number of moles of CO₂ produced = 35.0mol

Solution:

From the information given about the reaction, we know that the reactant that limits this combustion process is acetylene. Oxygen is given in excess and we don't know the number of moles of this gas that was used up. We know for sure that all the moles of acetylene provided was used to furnish the burning procedure.

To determine the number of moles of CO₂ produced, we use the stoichiometric relationship between the known acetylene and the CO₂ produced from the balanced chemical equation:

From the equation:

         2 moles of acetylene produced 4 moles of CO₂

          ∴ 35.0 mol of acetylene would produced:

[tex]\boxed{\text{ B. Increase the temperature and decrease the pressure.}}[/tex]

Explanation:

Let's say the reaction is

R ⇌ 2P; endothermic

I like to consider heat as if it were a reactant or a product in a chemical equilibrium.

Another way to write the equilibrium would be

heat + R ⇌ 2P

According to Le Châtelier's Principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

Let's consider each of the stresses in turn.

(i) Changing the temperature

If you want to increase the amount of product, you increase the temperature. The system will try to get rid of the added heat by shifting to the right, thus forming more product.

(ii) Changing the pressure

If R and P are liquids or solids or in aqueous solution, changing the pressure will have no effect. Something must be in the gas phase for a change in pressure to affect the position of equilibrium.

If P is a gas, the equilibrium is

heat + R ⇌ 2P(g)

Then, decreasing the pressure will produce more P. If you reduce the pressure, the system will respond by shifting to the right (the side with more gas molecules) to produce more P and bring the pressure back up

Answer:

above is wrong

Explanation:

Answer;

12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.

Explanation:

Using a balanced chemical equation we can identify the number of carbon, hydrogen, and oxygen atoms in sugar.

CxHyOn + 12O₂  → 11 H₂O + 12CO₂

When an equation is completely balanced, then the number of each atom of an element is equal on the reactant side and the product side.

Therefore;

For carbon; x = 12

For Hydrogen; y = (11×2) = 22

For Oxygen; n + (12×2) = 11 + (12×2)

                    = n + 24 = 11 + 24

                        n = 11

Therefore the sugar has, 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.
