We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, NH3. How many molecules of each type of gas will be present once the reaction has completed?
_ molecules hydrogen gas
_ molecules nitrogen gas
_ molecules ammonia gas

Even the smallest particle of a substance contains all of its physical and chemical properties. One or more atoms build up molecules.

What is reaction?

During a chemical reaction, one or more chemicals, sometimes referred to as "reactants," are transformed into one or more new compounds, sometimes referred to as "products." Both chemical components and elements are substances.

nitrogen gas = N2(g) --> 2 molecules 2N2(g)

hydrogen gas = H(g) --> 6 molecules 6H2(g)

ratio is;

N2 + 3H2 = 2NH3

assume 100% reaction so

2 molecules of N2 react to form 2*2 = 4 molecules of NH3

6 molecules of H2 react to form = the same 4 molecules of NH3

so

molecules of H2 left = 6-6 = 0 left

molecules of N2 left = 2-2 = 0 left

molecules of NH3 formed = 0 + 4 = 4 molecules of NH3 left.

Therefore, after the reaction the molecules of hydrogen and nitrogen are not left, only ammonia is 4 left.
