Sesh wants to create a device to transmit an electrical current. He has the following materials: pure water (H2O), brass (Cu3Zn2

) foil, solid calcium chloride (CaCl2), solid sugar (C12H22O11), pure methane (CH4), and a Bunsen burner. Describe two ways he could use these materials to transmit electricity. Assume that he has access to all necessary glassware and other equipment. Explain your choices using the properties of ionic, covalent, and metallic substances.

Here are two ways how he<span> could use these materials to transmit electricity: 

The first one is to carry the current due to the fact that metals conduct electricity in a needed condition only when they are solid.And since dissolved ionic compounds are good for conducting electricity - make a dissolving. Such materials as methane, water and sugar are not suitable as they are covalent compounds, that, as you know can not conduct an electric current.

Do hope it will help you!</span>

Use the brass foil to carry the current, because metals conduct electricity well in the solid state.


Dissolve the calcium chloride in water, because ionic compounds conduct electricity well when dissolved.


Pure water, sugar, or methane are not useful because they are covalent compounds and do not conduct an electric current.

You are asked to perform an experiment. When you perform the experiment you notice the vessel is warming. What type of reaction
Brut [27]

Exothermic type of reaction is taking place because this type of reaction generates heat energy.

<h3>What is exothermic reaction?</h3>

Exothermic reactions refer to those chemical reactions that produce heat energy and release that heat energy to the surrounding environment.

So we can conclude that exothermic type of reaction is taking place because this type of reaction generates heat energy.

What volume of nitrogen (n2) would be completely consumed in the reaction with 30.80 g of
Shtirlitz [24]

The answer is 285.33g nitrogen would be completely consumed in the reaction with 30.80 g of hydrogen gas.

<h3>What is a mole ?</h3>

A mole is defined as 6.02214076 × 10²³ atoms, molecules, ions, or other chemical units.

Write a balanced equation.

Calculate the moles of H₂ in 30.8 g.

Calculate the moles of N₂ required to react with H₂.

Calculate the mass of N₂.

Calculate the initial mass of N₂.

Start with a balanced equation.

N₂ + 3H₂ --> 2NH₃

Calculate the moles of H₂ in 30.8 g.

n = m/M; where n = moles, m = mass, and M = molar mass.

M(H₂) = 1.008 g/mol

n(H₂) = (30.8 g)/(1.008 g/mol) = 30.56 mol H₂

Calculate the moles of N₂ required to react with 30.56 mol H₂ , using the mole ratio between H₂ and N₂ in the balanced equation.

30.56 mol H₂ × 1 mol N₂/3 mol H₂ = 10.18 mol N₂

Calculate the mass of N₂ in 10.18 mol.

m = n × M

M(N₂) = 2 × 14.007 g/mol N = 28.014 g/mol N₂

m(N₂) = 10.18 mol × 28.014 g/mol = 285.33g N₂

Therefore 285.33g nitrogen would be completely consumed in the reaction with 30.80 g of hydrogen gas.
