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.

What effect does thermal energy have on the rate of chemical reactions?
Zielflug [23.3K]

Answer:

The temperature, however, greatly affects the rate of a chemical reaction. As you heat a substance, its molecules move faster and are more likely to react. Some reactants even require some heat to initiate a reaction. Reaction Rates and Temperature

A given way isotopes of nitrogen (N) contains 7 electrons,7 protons and 8 neutrons.
Murljashka [212]
Mass number is
protons + nuetrons
So,
7 + 8 = 15
——-
Atomic number is the number of protons
so,
