Answer: The mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
Explanation:
•Mole ratios are determined using the coefficients of the substances in the balanced chemical equation. •Each coefficient represents the number of mole of each substance in the chemical reaction.
•The mole ratio can be determined by first writing out a balanced chemical equation for the reaction.
For this reaction the balanced chemical equation is
N2(g) + 3H2(g) ----> 2NH3(g)
1mol:3mol : 2mol
From the equation we can see that 1 mole of N2(g) reacts with 3 moles of H2(g) or 3 moles of H2(g) react with 1 mole of N2(g) to produce 2 moles of NH3(g).
Therefore, the mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
Covalent bonds in solution, hydrogen bonds in solution, ionic bonds in solids, nonpolar covalent bonds in solids- the weakest bond is hydrogen bond.
What is a chemical bond?
A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. Strong bonds, also known as primary bonds, include covalent, ionic, and metallic ties. Weak bonds, also known as secondary bonds, include dipole-dipole interactions, the London dispersion force, and hydrogen bonds.
Since there is no necessity for an electron exchange during formation, the hydrogen bond is weak. As a result, it is simpler to break apart a hydrogen connection between two molecules.

We will assume that the question is discussing 1.000 atm of N₂ initially. The question is discussing diffusion rates of two gases and asks us to identify the species. We can use Graham's Law to attempt this problem with the following formula:
Rate₁/Rate₂ = sqrt(M₂/M₁)
We are told that the N₂ is 3.55 times as fast as the unknown species, so rate 1 = 3.55 and rate 2 = 1. We know the molecular weight of N₂ as 28 g/mol. Now we can use the equation above to solve for the molecular weight of the unknown, M₂:
3.55/1 = sqrt(M2/28)
(3.55)² = M₂/28
M₂ = 28 (3.55)₂
M₂ = 353 g/mol
The unknown compound has a molecular mass of roughly 353 g/mol and this is very close to the molecular mass of UF₆ which is 352.02 g/mol. Therefore, it is likely that the unknown gas is UF₆.
