Answer:
The new pressure will increase.
Explanation:
If the temperature in a tank increases, the pressure inside the tank will also increase. This is one of the postulates of the general gas law.
Pressure exerted by a gas is it's force per unit area.
When we reduce the equation of the combined gas law taking the number of moles to be 1, we see that;"at constant volume, the pressure of a given mass or mole of gas varies directly with the absolute temperature" .
The higher the pressure, the higher the temperature will be.
Since the complete parameters are not given, use this expression below:
[tex]\frac{P_{1} }{T_{1} } = \frac{P_{2} }{T_{2} }[/tex]
where P and T are pressure and temperature
1 and 2 represents initial and final states.
The new pressure in the tank when the temperature is increased to 85°C can be calculated using Charles's Law, which requires converting temperatures to Kelvin and then applying the formula P1/T1 = P2/T2.
Explanation:To calculate the new pressure in the tank when the temperature is increased to 85°C, we can apply Charles's Law, which states that for a fixed amount of gas at constant volume, the pressure is directly proportional to its temperature in Kelvin. This implies that if the temperature increases, the pressure will also increase proportionally. To find the new pressure P₂, we use the equation P₁/T₁ = P₂/T₂, where P₁ is the initial pressure, T₁ is the initial temperature, P₂ is the final pressure, and T₂ is the final temperature.
For example, if a gas tank has an initial pressure P₁ of 1.0 atm at a temperature of 20°C (which is 293.15 K when converted to Kelvin), and the temperature is increased to 85°C (358.15 K in Kelvin), the new pressure P₂ can be calculated as follows:
P₂ = P₁ × (T₂ / T₁)
P₂ = 1.0 atm × (358.15 K / 293.15 K)
P₂ would then be calculated to find the pressure at the higher temperature.
2 C2H6 + 7 02 -> 4CO2 + 6H2O
If 15 g of C2H6 react with 45 g of O2, how many grams of water will be produced?
Answer:
Mass of water = 21.6 g
Explanation:
Given data:
Mass of C₂H₆ = 15 g
Mass of O₂ = 45 g
Mass of water produced = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Number of moles of C₂H₆:
Number of moles = mass/ molar mass
Number of moles = 15 g/ 30 g/mol
Number of moles = 0.5 mol
Number of moles of O₂ :
Number of moles = mass/ molar mass
Number of moles = 45 g/ 32 g/mol
Number of moles = 1.4 mol
Now we will compare the moles of C₂H₆ and O₂ with H₂O.
C₂H₆ : H₂O
2 : 6
0.5 : 6/2×0.5 = 1.5
O₂ : H₂O
7 : 6
1.4 : 6/7×1.4 = 1.2
The number of moles of water produced by oxygen are less so it will limiting reactant.
Mass of water produced:
Mass = number of moles × molar mass
Mass = 1.2 mol × 18 g/mol
Mass = 21.6 g

If an atom loses and electron what type of ion does it form?
Answer
cation
Explanation:
If an atom losses electrons it forms a positively charged ion called the cation.
cation has more protons than electrons, thereby giving it a net positive charge.
To form a cation one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. zinc (Zn) loses two electrons to become Zn2+.

How can you use mass and volume to find density of a substance ?
Answer:
mass=density x volume
Explanation:
Final answer:
Density can be calculated by dividing the mass of a substance by its volume. The formula is Density = mass / volume.
Explanation:
The density of a substance can be calculated by dividing its mass by its volume. For example, let's say we have a sample of a substance with a mass of 50 grams and a volume of 20 cubic centimeters. To find the density, we would divide the mass by the volume:
Density = mass / volume
So in this case, the density would be:
Density = 50g / 20 cm3 = 2.5 g/cm3
Thus, the density of the substance is 2.5 grams per cubic centimeter.

You have 500 mL of 5 M HCl already made. You need to dilute the solution to 1 M HCl. How much water will you need to add?
Answer: 2500 ml
Explanation:
To dilute a 500 mL solution of 5 M HCl to a 1 M HCl solution, 2000 mL of water must be added, using the formula M1V1 = M2V2 with the values substituted respectively.
The question involves diluting a concentrated solution to a lower concentration, specifically diluting a 500 mL solution of 5 M HCl to obtain a 1 M HCl solution. To solve this, the dilution equation, M1V1 = M2V2, is used. In this equation, M represents molarity, and V represents volume. Initially, we have M1=5 M, V1=500 mL, and M2=1 M. We need to find V2, the final volume after dilution.
Step 1: Identify known variables: M1 = 5 M, V1 = 500 mL, M2 = 1 M.Step 2: Substituting known values into the equation 5 M * 500 mL = 1 M * V2.Step 3: Solve for V2: V2 = (5 * 500) / 1 = 2500 mL. This is the final volume after dilution.Step 4: Calculate the amount of water needed to dilute the solution: Volume of water added = V2 - V1 = 2500 mL - 500 mL = 2000 mL.Therefore, to dilute the 500 mL solution of 5 M HCl to a 1 M solution, 2000 mL of water needs to be added.
What major factors play a role in global warming
Global warming is primarily driven by human activities that release greenhouse gases into the atmosphere.
The burning of fossil fuels (coal, oil, and natural gas) for energy production and transportation is the largest contributor, releasing carbon dioxide (CO₂) and methane (CH₄). Deforestation and land-use changes also play a significant role, as trees absorb CO₂, but their removal releases it back into the atmosphere.
Industrial processes, agriculture, and waste management release additional greenhouse gases. These gases trap heat in the Earth's atmosphere, leading to an increase in average global temperatures, disruptions in weather patterns, rising sea levels, and other climate-related impacts.

A sample of iron with a mass of 50.0 grams absorbs 2500 J of thermal energy. How much would the temperature of this sample change as a result of absorbing this amount of heat?
Temperature change would be 112.6° C.
Explanation:
We can find the amount or heat absorbed or emitted during any reaction by finding the product of their mass, specific heat, and change in temperature of the metal.
Mass of the iron, m = 50.0 g
Amount of heat absorbed, q = 2500 J
Change in temperature, ΔT = ?
Specific heat of Iron, C = 0.444 J/g °C
[tex]\boldsymbol{q}=\boldsymbol{m} \times \boldsymbol{C} \times \boldsymbol{\Delta} \mathbf{T}[/tex]
Plugin the values and rearrange the equation to get the change in temperature as,
[tex]\Delta \mathbf{T}=\frac{\mathbf{q}}{c \times m}[/tex]
[tex]\Delta \mathrm{T}=\frac{2500 \mathrm{J}}{0.444 \frac{J}{\mathrm{g}^{\circ} \mathrm{C}} \times 50 \mathrm{g}}=112.6^{\circ} \mathrm{C}[/tex]
The temperature of the iron sample would change by approximately [tex]\( 111.11 \, ^\circ \text{C} \)[/tex] as a result of absorbing 2500 J of thermal energy.
To determine the change in temperature of the iron sample, we need to use the specific heat capacity formula [tex]\[ q = m \cdot c \cdot \Delta T \][/tex]
where:
[tex]- \( q \)[/tex] is the amount of heat absorbed or released (in joules),
[tex]- \( m \)[/tex] is the mass of the substance (in grams),
[tex]- \( c \)[/tex] is the specific heat capacity of the substance (in joules per gram per degree Celsius),
[tex]- \( \Delta T \)[/tex] is the change in temperature (in degrees Celsius).
For iron, the specific heat capacity [tex]\( c \)[/tex] is approximately [tex]\( 0.450 \, \text{J/g}^\circ \text{C} \)[/tex].
Given:
[tex]- \( q = 2500 \, \text{J} \), - \( m = 50.0 \, \text{g} \), - \( c = 0.450 \, \text{J/g}^\circ \text{C} \).[/tex]
We can rearrange the formula to solve for [tex]\( \Delta T \)[/tex]:
[tex]\[ \Delta T = \frac{q}{m \cdot c} \][/tex]
Now, plug in the values:
[tex]\[ \Delta T = \frac{2500 \, \text{J}}{50.0 \, \text{g} \cdot 0.450 \, \text{J/g}^\circ \text{C}} \] \[ \Delta T = \frac{2500}{50.0 \times 0.450} \] \[ \Delta T = \frac{2500}{22.5} \] \[ \Delta T \approx 111.11 \, ^\circ \text{C} \][/tex]
The answer is: [tex]111.11 \, ^\circ \text{C}[/tex].

Any species that undergoes oxidation is itself a reducing agent or reductant.
The species that undergoes reduction in the course of a chemical reaction is an oxidant or reducing agent.
Oxidation is defined as the loss of electrons, addition of oxygen and increase in oxidation number of a specie. Reduction is the gain of electrons, removal of oxygen and decrease in oxidation number of a specie.Any specie that loses electrons to another undergoes oxidation and is a reductant.
Species that gains electrons are called oxidant.
Analysis of a rock sample shows that it contains 6.25% of its original uranium-235. How old is the rock? How do you know?
Answer:
[tex]2.82\cdot 10^9 y[/tex]
Explanation:
A radioactive isotope is an isotope that undergoes nuclear decay, breaking apart into a smaller nucleus and emitting radiation during the process.
The half-life of an isotope is the amount of time it takes for a certain quantity of a radioactive isotope to halve.
For a radioactive isotope, the amount of substance left after a certain time t is:
[tex]m(t)=m_0 (\frac{1}{2})^{\frac{t}{\tau}}[/tex] (1)
where
[tex]m_0[/tex] is the mass of the substance at time t = 0
m(t) is the mass of the substance at time t
[tex]\tau[/tex] is the half-life of the isotope
In this problem, the isotope is uranium-235, which has a half-life of
[tex]\tau=7.04\cdot 10^8 y[/tex]
We also know that the amount of uranium left in the rock sample is 6.25% of its original value, this means that
[tex]\frac{m(t)}{m_0}=\frac{6.25}{100}[/tex]
Substituting into (1) and solving for t, we can find how much time has passed:
[tex]t=-\tau log_2 (\frac{m(t)}{m_0})=-(7.04\cdot 10^8) log_2 (\frac{6.25}{100})=2.82\cdot 10^9 y[/tex]
Which substance below has the greatest mass?
1 mole of silver
1 mole of copper
1 mole of lead
1 mol of tungsten
1 mole of lead has the greatest mass because its molar mass of approximately 207.2 g/mol is higher than that of silver (107.87 g/mol), copper (63.55 g/mol), and tungsten (183.84 g/mol), and all samples contain Avogadro's number of atoms.
Explanation:To determine which substance has the greatest mass, we need to compare the molar masses of silver, copper, lead, and tungsten. The molar mass is the mass in grams of one mole of a substance, and it is numerically equivalent to the atomic mass for elements. Let's examine the atomic masses of these elements:
Silver (Ag): Approximately 107.87 g/molCopper (Cu): Approximately 63.55 g/molLead (Pb): Approximately 207.2 g/molTungsten (W): Approximately 183.84 g/molGiven that 1 mole of each substance contains the same number of atoms (6.022 × 10²23 atoms, Avogadro's number), the substance with the highest molar mass will have the greatest mass. In this case, lead has the highest molar mass at approximately 207.2 g/mol, and therefore 1 mole of lead will have the greatest mass compared to 1 mole of silver, copper, or tungsten.
Final answer:
Lead (Pb) has the greatest mass.
Explanation:
The substance with the greatest mass in this case would be lead (Pb).
To determine which substance has the greatest mass, we need to compare their molar masses. The molar mass of silver (Ag) is approximately 107.87 g/mol, copper (Cu) is approximately 63.55 g/mol, lead (Pb) is approximately 207.2 g/mol, and tungsten (W) is approximately 183.84 g/mol.
Since lead (Pb) has the highest molar mass of the four substances, it has the greatest mass.

NaClo3→
what is the reactant?
Answer:
NaClo3 is the reactant here.
Explanation:
In any chemical reaction there is reactant and product. The one that takes part in chemical reaction is called as reactant. For example:In the reaction below:
[tex]H_{2} + O_{2}[/tex] ----------------------> 2[tex]H_{2} O[/tex]
Here [tex]H_{2}[/tex] and [tex]O_{2}[/tex] are reactant, they take part in chemical reaction to form water as a product.
So the left hand side in a reaction equation always denotes the reactants. As in our question NaClo3 is in the left part of the reaction, it is the reactant.Identify the missing coefficient in the balanced equation and classify the type of reaction.
Cl2O3 + H20- HCIO3
Final answer:
The missing coefficient in the reaction Cl2O3 + H2O → HCIO3 is 2 in front of HCIO3, resulting in a balanced equation Cl2O3 + H2O → 2 HCIO3, which is a combination reaction.
Explanation:
The missing coefficient in the chemical equation Cl2O3 + H2O → HCIO3 should balance the number of atoms of each element on both sides of the equation. In this case, to balance chlorine and oxygen atoms, we should place a coefficient of 2 in front of HCIO3, resulting in Cl2O3 + H2O → 2 HCIO3. This is an example of a combination reaction, where two or more substances combine to form a single product. Below are several examples of different reaction types for context:
a. Combustion reaction: C6H5CH3 + 9O2 → 7CO2 + 4H2Ob. Decomposition reaction: 2NaHCO3 → Na2CO3 + H2O + CO2c. Synthesis reaction: C + 2H2 → CH4
10.6 grams of Na2CO3 is dissolved in water to make 1.25 liters
of solution. What is the molarity of the solution? (Molar mass of
Na2CO3 = 106 g/mol) __M.
Answer:
Molarity = 0.08 M
Explanation:
Given data:
Mass of sodium carbonate = 10.6 g
Volume of water = 1.25 L
Molarity of solution = ?
Solution:
First of all we will calculate the moles of solute.
Number of moles = mass/molar mass
Number of moles = 10.6 g/ 106 g/mol
Number of moles = 0.1 mol
Formula:
Molarity = moles of solute / volume of solution in L
Now we will put the values in formula.
Molarity = 0.1 mol / 1.25 L
Molarity = 0.08 M

Lithium acetate is composed of lithium ions [tex](Li^+)[/tex] and acetate ions [tex](C_2H_3O_2^-)[/tex].
The formula indicates that for each lithium ion, there is one acetate ion. In chemical formulas, the subscripts indicate the number of atoms of each element present in the compound.
In this case, "Li" represents lithium, "C" represents carbon, "H" represents hydrogen, and "O" represents oxygen.
So, the formula [tex]LiC_2H_3O_2[/tex] indicates that there is one lithium atom, two carbon atoms, three hydrogen atoms, and two oxygen atoms in lithium acetate.
How do we get mass number
Explanation:
The mass number of an element's atom is gotten by adding the number of protons and neutrons of the atom. Electrons have negligible mass compared to the protons and neutrons hence do not matter. The mass of a nuclear particle ( protons and the neutrons) is based on the 1/12 mass of carbon which is used as the standard for getting the mass of other elements.
If an element has isotopes the relative mass of the element is gotten by adding all the atomic mass numbers of the isotopes and dividing the sum by the number of isotopes.
What does the environment where sediments are deposited mean for the rock that eventually forms?
Please Help!
Thanks
Answer with Explanation:
The environment where the sediments are deposited gives an information regarding the rock that eventually forms.
The minerals and textures of the rocks can tell what kind of environment they were formed as they were being deposited. The fossils embedded in the rocks (sedimentary rocks) or the outcrops can also tell what happened on earth during those times. The process of rock accumulation also tells whether there was a high level of flood, strong winds or sub-arctic environments occurring.
This then gives an evidence of the earliest life forms on Earth.
Final answer:
The depositional environment where sediments are collected has a direct impact on the type of sedimentary rock that forms, with factors such as available oxygen affecting characteristics like rock color. This information helps geologists reconstruct past Earth conditions and ecosystems.
Explanation:
The environment where sediments are deposited has significant implications for the sedimentary rock that will eventually form. For instance, beaches and deserts accumulate large deposits of sand, potentially forming sandstone, while the deep ocean floor might host sediments that turn into shale or limestone.
Depositional environments impart specific characteristics to the resulting rocks. Examples of this include the presence of oxygen influencing rock color during and after sediment burial. Understanding these environments allows geologists to reconstruct past Earth conditions and the history of life on our planet.
Sedimentary rocks from one environment might share similar types but can also be found across varying conditions, making pinpointing the depositional environment a challenging task. Yet, clues like sediment properties, rock color, and the presence of fossils provide invaluable insights into the ancient environments where these rocks formed.

In ionic bonds, valence electrons are
Answer:
Valence Electrons are transferred/exchanged
In ionic bonds, valence electrons are transferred from one atom to another, leading to the formation of oppositely charged ions that attract each other to create the bond.
In ionic bonds, valence electrons are transferred from one atom to another. This process involves the movement of electrons from an atom that has a relatively low number of electrons in its valence shell (often a metal) to an atom with a higher affinity for electrons (often a nonmetal), which has a relatively high number of electrons in its valence shell or a few electrons short of completing its shell. Through this transfer, the atom losing electrons becomes a positively charged ion (cation), and the atom gaining electrons becomes a negatively charged ion (anion). This electrostatic attraction between the oppositely charged ions forms the ionic bond. For example, in the formation of sodium chloride (NaCl), sodium (Na) loses one electron to become Na⁺, while chlorine (Cl) gains that electron to become Cl⁻, resulting in a stable ionic compound.
The complete question is:
Fill in the blanks:
In ionic bonds, valence electrons are _______.
