Since the question is incomplete, here I copy the full question:

Consider the following reaction:

A reaction mixture contains 5 moles of NO and 10 moles of H₂. Without doing any calculations, determine which of the following best represents the mixture after the reactants have reacted as completely as possible. Explain your reasoning.

a) 1 mol NO, 0 mol H₂, 4 mol NH₃, 4 mol H₂O

b) 0 mol NO, 1 mol H₂, 5 mol NH₃, 5 mol H₂O

c) 0 mol NO, 0 mol H₂, 4 mol NH₃, 4 mol H₂O

d) 3 mol NO, 5 mol H₂, 2 mol NH₃, 2 mol H₂O

Explanation:

The coefficients of the balanced chemical equation gives the stoichiometric mole ratios; this is, the proportion of the number of moles of each reactant that indeed react and the number of moles that can be yielded of each product .

Thus, from the balanced chemical equation, the mole ratios are:

Now, the starting mixture contains 5 moles of NO and 10 moles of H₂, so:

         Summarizing: after the reaction, there will be 1 mol NO and 0 mol H₂.

At the end, you have determined, without calculations, that the mixture after the reactants have reacted as completely as possible, is represented by the first option:

The mixture after the reactants have reacted

1 mol NO, 0 mol H₂, 4 mol NH₃, 4 mol H₂O

The reaction equation is the chemical formula of reactants and products

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reactants and products

Reaction

2NO (g) + 5 H₂ (g) → 2 NH₃ (g) + 2H₂O (g)

There are initially 5 moles of NO and 10 moles of H₂

The method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and the small quotient will be used up or as a limiting reactants

If we look at the ratio of moles to their coefficients, H₂ is smaller than NO, so H₂ becomes the limiting reactants

Because H₂ becomes the limiting reactants, then the mole will react all, so that the rest of the reaction when equilibrium = 0

From the available answer choices, only choices a and c show the mole of H₂ = 0

From these choices (a and c), choice c shows that mole NO is also 0. This is not possible because there are residual reactions from mole NO because the ratio of reaction coefficient and mole ratio is not the same between H₂ and NO

So the right choice is

a) 1 mol NO, 0 mol H mol, 4 mol NH₃, 4 mol H₂O
