<h3>Answer: False</h3>

In solid form, ionic compounds do not conduct electricity. Ionic compounds will conduct electricity when melted to their liquid state. This is due to the electrons being locked in place when in solid form, but liquid form allows for the electrons to move freely.

A 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. The re

The mass of nickel is 36.5g metal.

Ni+2AgNO3 → Ni(NO3)2+2Ag

21.5g Ni / 58.69g = 0.366mol Ni

Ag = 107.87

N i= 58.69

But, 2molAg per 1 mol Ni, so, change in mass is more like...

Twice as many moles Ag as Ni, and then the mass relationship is 107.87g Ag / 58.69, but due to the 2Ag: 1Ni mol ratio, the change in mass is like:

107.87(2) / 58.69 = 3.68 times increase

So, the final mass of Ag is 3.68x, and the change in mass of Ni is x

36.5=(21.5-x)+(3.68x)

Solve for x

x=5.597

3.68x=g Ag

3.68(5.597)=20.59

21.5 - x = g Ni after reaction

21.5 - 5.597 = 15.903g Ni

20.59g Ag + 15.903g Ni = 36.5g metal

The mass of nickel is 36.5g metal.

Light energy (in both visible and invisible forms) is a form of _____ energy.

Ainat [17]

Answer:

D: Electromagnetic

Explanation:

Chemical energy is the energy in chemical bonds which is a type of potential energy, eliminating both B and C. While kinetic energy is the energy of motion, photons are a wave/ particle so thinking it would have kinetic energy wouldn't be your fault but light is on the electromagnetic spectrum making D the most likely answer.

A sample of oxygen gas was found to effuse at a rate equal to two times that of an unknown gas. The molecular weight of the unkn

Pie

Answer: 128 g/mol

Explanation:

Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles.

Mathematically, that is:

$\frac{Rate_1}{Rate_2}=\sqrt{\frac{MolarMass_2}{MolarMass_1} }$

Since, you know the ratio of two rates and the molar mass of one gas, you can calculate the molar mass of the other gas.

The molar mass of the oxygen molecule, O₂ = 2×16.0g/mol = 32.0 g/mol.

In the coming equations, I will use 32 g/mol for simplicity of writing.

$\frac{Rate_1}{Rate_2}=2 \\ \\ \\ MolarMass_1=32g/mol\\\\\\ 2=\sqrt{\frac{MolarMass_2}{32g/mol} } \\ \\ \\ 4=\frac{MolarMass_2}{32g/mol}\\ \\ \\ MolarMass_2=128g/mol$

So, the molecular mass of the unnknown gas is 128 g/mol.

If 7.25g of chlorine is reacted with excess hydrogen and produces 7.25 g HCl. What is the percent yield?

lozanna [386]

Answer:

94.61 %

Explanation:

percent yield = (actual yield / theoretical yield) X 100%

The balanced equation for the reaction is:

H2 (g ) + Cl2(g) => 2 HCl (l)

So, the theoretical yield =

7.25g of chlorine X (2mol of Cl / 35.453 g of Cl) X (2mol Cl / 2mol of HCl) X 37.469g of Hcl / 2mol of Hcl = 0.409 x 18.735 = 7.663g of Hcl

Using this theoretical yield and the provided value for actual yield, the percent yield = (actual yield / theoretical yield) X 100%

= (7.25 g / 7.663g) X 100

= 94.61 %
