Two things that must be in circuits to make them work are a conductor and a voltage source.

Explanation:

There are tow main parts that helps all electric circuits to work. They are a conductor and a voltage source. Some of the other parts of circuits includes,switches and bulbs. The working of an electrical circuit is same as that of the human circulatory system. The blood is taken to all parts of human body with the help of the blood vessels in a circulatory system.

Same thing happens with an electrical circuit. This is responsible in taking current to all parts of an electrical system. In an electrical circuit electricity will flow from the voltage of high to low. A path should be there for conducting the electric power.

Answer:

Yes, the unknown substance is the liquid ethylene glycol.

Explanation:

Here the density of the unknown substance is 69.22lb/f and the density of ethylene glycol, the liquid used in antifreeze is 1.1088g/ml

We know, 1g  = 0.0022lb

1ml= [tex]3.531 \times 10^{-5} ft^3[/tex]

Therefore, 1g/ml = 62.428[tex]lb/ft^3[/tex]

Since, the density of ethylene glycol = 1.1088g/ml

 = 1.1088 [tex]\times[/tex] 62.428 [tex]lb/ft^3[/tex]

= 69.22 [tex]lb/ft^3[/tex]

When the density of ethylene gas is converted from g/ml unit to [tex]lb/ft^3[/tex] unit, it is found to have the same value (69.22)Therefore, the unknown substance here is liquid ethylene glycol.

Answer:

Salt is ionic, and oil is covalent. If you add water, the salt will dissolve in the water, and the oil will float to the top. You could then skim the oil and start over with sugar. To double-check, you could even make sure the oil does not conduct electricity!

Explanation:

just took on edge 2020

Removing salt from oil is difficult and complex, requiring particular separation processes. In most domestic situations, it's more feasible to discard the oil and start fresh.

When you accidentally add salt to the oil instead of sugar, it becomes a bit problematic to remove it. This is because both oil and salt are not miscible with water and the salt has likely dissolved into the oil. Removing the salt would need a separation process, such as centrifuge separation or sequential filtration. Unfortunately, these methods are complex and usually not readily available in a typical domestic environment.

As a simple solution, it might be more feasible to discard the salted oil and start fresh. This would save time and ensure that no unwanted salty flavor is incorporated into your food preparation.

Final answer:

Despite having strong C-H and C-Cl bonds, dichloromethane is liquid due to strong dipole-dipole intermolecular forces and van der Waals forces resulting from its considerable dipole moment and molecular size.

Explanation:

The question asks why dichloromethane is a liquid despite having strong carbon-hydrogen (C-H) and carbon-chlorine (C-Cl) bonds. While the individual molecular bonds within dichloromethane are indeed strong (due to significant differences in electronegativity between carbon, hydrogen, and chlorine), the phase state (gas, liquid, or solid) of a substance at room temperature depends on the intermolecular forces between its molecules, not just the strength of the bonds within individual molecules. Dichloromethane, having a considerable dipole moment due to its polar C-Cl bonds, exhibits stronger intermolecular forces known as dipole-dipole interactions. These interactions, though weaker than covalent bonds, are significantly strong enough to keep the molecules close together in a liquid state at room temperature. Additionally, the molecular weight and size of dichloromethane contribute to stronger van der Waals forces (or London dispersion forces), which further supports its liquid state. Unlike smaller molecules that might be gases at room temperature, dichloromethane has just the right balance of molecular weight and intermolecular forces to exist as a liquid.

Proportionality that applies to avogadro's law is V is propportional to n.

According to Avogadro's law, equal volumes of various gases each contain an equal amount of molecules at the same temperature and pressure. On the presumption of an ideal (perfect) gas, this experimental relation can be deduced first from kinetic theory of gases. For actual gases, the law is roughly applicable when temperatures and pressures are both low enough.

Avogadro's number, or even the Avogadro constant, is the precise quantity of molecules inside one gram-mole of such a material, defined as that of the molecular weight metric grams, which is equal to 6.022×10²³.

Answer:

More energy will be released from the old substance than the new substance will need to form it's chemical bonds.

Explanation:

Given

Chemical A and Chemical B react in an exothermic reaction.

This means energy is released when they react to give products. The product formation also requires energy, which is got from the energy released when A and B reacts. The energy that is left after the formation of products is released as heat. So in order for a reaction to be exothermic, the energy released  by the reactants should be more than the energy required for the new chemical bonds to be formed to give the products.

Explanation:

Answer:

The answer is B.

Explanation:

This type of bond is formed when the electrons are shared equally between the atoms. This type of bond is termed as non-polar because of the electronegativity difference between the atoms is negligible.

The electrons in a bond between two iodine atoms are shared equally, resulting in a nonpolar covalent bond because both atoms have the same electronegativity and pull on the electrons to the same extent.

The electrons in a bond between two iodine atoms (I2) are shared equally, and since both atoms have the same electronegativity, they pull on the electrons to the same extent. This lack of asymmetry in the electrical charge distribution means that the resulting bond is nonpolar. Therefore, the correct answer to the question is: b. Equally, and the resulting bond is nonpolar.

When atoms like iodine, which are identical, form a covalent bond, they have the same tendency to attract shared electrons, resulting in an even distribution of electron density. This equal sharing of electrons characterizes a nonpolar covalent bond.

Answer:

8.8 cm³

Explanation:

Data given:

volume of Liquid = 0.0088 L

convert volume to Cubic centimeters

Solution:

There are number of unit in which volume can be measured

As

Liter is unit of volume represented by L

Cubic centimeters represented by cm³

liter is larger value then cm³

Now to convert L to cm³

As we Know

1 L = 1000 cm³

So

Apply unity formula

           1 L = 1000 cm³

           0.0088 L = x cm³

Do Cross multiplication

            x cm³ = 0.0088 L x 1000 cm³ /  1 L

            x cm³ = 8.8 L.cm³ /  1 L

            x cm³ = 8.8 cm³

So,

0.0088 L of liquid = 8.8 cm³

Final answer:

To convert 0.0088 liters to cubic centimeters, multiply by the conversion factor of 1,000. This yields a volume of 8.8 cubic centimeters.

Explanation:

In a fluid, the particles are still in close contact, so fluids have an unmistakable volume. In any case, in light of the fact that the particles can move about one another fairly openly, a fluid has no positive shape and takes a shape directed by its compartment.

To convert the volume of a liquid from liters to cubic centimeters, we can use the conversion factor that 1 liter is equivalent to 1,000 cubic centimeters (cm³). Since 1 milliliter (mL) is also equivalent to 1 cubic centimeter (cm³), we first convert liters to milliliters before converting to cubic centimeters.

The volume given is 0.0088 L. To convert this to milliliters, we multiply by the conversion factor:

0.0088 L × 1,000 mL/1 L = 8.8 mL

Now, since 1 mL is equal to 1 cm³, the volume in cubic centimeters is:

8.8 cm³

Answer:

Explanation:

Data given:

mass of Al  = 160.0 g

actual yield Al₂O₃= 260 g

Theoretical yield = ?

percent yield ofAl₂O₃ = ?

Solution:

First we have to find theoretical yield.

So,

we Look at the balanced reaction

             4Al  + 3O₂ -----—> 2Al₂O₃

             4 mol                      2 mol

As 4 mole of Al give 2 mole of Al₂O₃

Convert moles to mass

molar mass of Al = 27 g/mol

molar mass of Al₂O₃ = 2(27) + 3(16)

molar mass of Al₂O₃ = 54 + 48

molar mass of Al₂O₃ = 102 g/mol

Now

             4Al         +       3O₂   -----—>     2Al₂O₃

        4 mol (27g/mol)                       2 mol (102 g/mol)

             108 g                                            204 g

108 grams of Al produce 204 g of Al₂O₃

So

if 108 grams of Al produce 204 g of Al₂O₃ so how many grams of Al₂O₃ will be produced by 160 g of Al.

Apply Unity Formula

              108 grams of Al  ≅ 204 g of Al₂O₃

              160 grams of Al ≅ X of Al₂O₃

Do cross multiply

              mass of Al₂O₃= 204 g x 160 g / 108 g

              mass of Al₂O₃ = 302.2 g

So the Theoretical yield of Al₂O₃ = 302.2 g

Now Find the percent yield of Al₂O₃

Formula Used

             percent yield = actual yield /theoretical yield x 100 %

Put value in the above formula

            percent yield = 260g / 302.2 g x 100 %

            percent yield = 86.04 %

percent yield of Al₂O₃ = 86.04 %

Final answer:

The theoretical yield is 302.3 grams of Al2O3, and the percent yield is 86.0%, found by comparing the actual yield of 260.0 grams to the theoretical yield.

Explanation:

The question asks us to calculate the theoretical yield and percent yield when burning aluminum (Al) to produce aluminum oxide (Al2O3). The mass of Al used is 160.0 grams, and the amount of Al2O3 produced is 260.0 grams.

To calculate the theoretical yield, we first need to use the stoichiometry of the balanced reaction:
4Al(s) + 3O2(g) → 2Al2O3(s).

Next, convert the given mass of Al to moles using its molar mass (27.0 g/mol):
(160.0 g Al) / (27.0 g/mol Al) = 5.93 moles Al

According to the stoichiometry, 4 moles of Al produce 2 moles of Al2O3, so:
(5.93 moles Al) x (2 moles Al2O3 / 4 moles Al) = 2.965 moles Al2O3

Then convert moles of Al2O3 to grams using its molar mass (101.96 g/mol):
(2.965 moles Al2O3) x (101.96 g/mol Al2O3) = 302.3 grams Al2O3

This is the theoretical yield. The percent yield is calculated as follows:
(Actual Yield / Theoretical Yield) x 100
(260.0 g / 302.3 g) x 100 = 86.0%

The chemist achieved an 86.0% percent yield.

Scientists discovered Earth's outer core is liquid because shear waves from earthquakes do not pass through it, while compression waves do. Inge Lehmann interpreted seismic data to confirm this structure. The core's heat is maintained by the radioactive decay of elements.

The question relates to how scientists discovered that Earth's outer core is liquid. Inge Lehmann played a pivotal role in interpreting seismological data from earthquakes. It was observed that shear waves, which cannot travel through liquid, do not transmit through the Earth's core, unlike compression waves, which do. This was key evidence indicating that the outer core was liquid.

Since shear or transverse waves are not transmitted through the Earth's outer core, but longitudinal waves pass through, it indicated differing properties consistent with a liquid outer core and a solid inner core. The Earth's core was found to consist of a liquid outer core surrounding a solid inner core, made of materials like iron and nickel. The composition and presence of these elements also led to the creation of Earth's magnetic field.

The substantial heat of the Earth's interior, despite the expectation of cooling over 4.5 billion years, is maintained by the radioactive decay of primordial elements. The density of the mantle rock increases with depth and occasionally is studied when ejected from volcanoes, bearing detailed chemistry for analysis.

Answer:

                    0.412 Kg of Solution

Explanation:

                    To solve this problem we will first find the number of grams of solute contained by the given amount of solution as,

                      w/w%  =  weight of solute / weight of solution × 100

Solving for weight of solute,

                      Weight of solute = w/w% × weight of solution / 100

Putting values,

                      Weight of solute = 10.9 × 500 g / 100

                       Weight of solute = 54.5 g

Hence,

                  54.5 g of solute was contained by  =  500 g of solution

So,

               45.0 g of solute will be contained by  =  X g of solution

Solving for X,

                     X =  45.0 g × 500 g / 54.5 g

                      X =  412.84 g

Or,

                     X  =  0.412 Kg of Solution

Final answer:

To obtain 45.00g of 4-methyl-2-pentanone from a 10.9% w/w solution, the student should measure out 412.84g of the solution.

Explanation:

To calculate the mass of the solution the student should use to get 45.00g of 4-methyl-2-pentanone from a 10.9% w/w solution, we first need to understand what a w/w solution means. It indicates that for every 100g of solution, there is 10.9g of the solute (4-methyl-2-pentanone). To find the mass of the solution needed for 45.00g of the solute, the following calculation should be performed:

Mass of solute (desired) = % w/w × mass of solution
Therefore, mass of solution = Mass of solute (desired) / % w/w

So:

Mass of solution = 45.00g / 0.109 = 412.84g

The student should therefore measure out 412.84g of the 10.9% solution to obtain 45.00g of 4-methyl-2-pentanone.

Answer:

Option A is correct: You have three times the number of particles that are in 12 grams of carbon-12

Explanation:

Data given:

3 moles of substance equal to how many particles of 12 g of carbon-12.

Solution:

First we find the number of particles in 3 moles of substance

Formula used

          no. of moles = no. of particles / Avogadro's number

Rearrange the above formula

         no. of particles = no. of moles x Avogadro's number . . . . . . . . (1)

Where

Avogadro's number = 6.022 x 10²³

Put values in above equation

      no. of particles = 3 x 6.022 x 10²³ (particles/mol)

      no. of particles = 1.8066 x 10²⁴ Particles

So,

3 mole of substance have 1.8066 x 10²⁴ Particles

Now

we have to find number of particles in 12 g of carbon-12

for this first find no. of moles

formula used

       no. of moles = mass in grams/ molar mass . . . . . (2)

molar mass of carbon = 12 g/mol

Put values in equation 2

       no. of moles = 12 g / 12 (g/mol)

       no. of moles = 1 mole

So,

12 g of carbon 12 equal to 1 mole.

According to Avogadro's law 1 mole of any substance consists of 6.022 x 10²³ number of particles.

So

1 mole carbon = 6.022 x 10²³ particles

and 3 mole of substance = 1.8066 x 10²⁴ Particles

It means that we have three times number of particles that are in 12 g of carbon-2

So, Option A is correct.

A. You have three times the number of particles that are in 12 grams of carbon-12.
