To determine the number of moles of hydrogen needed to react with 2.6 moles of nitrogen in the given balanced chemical equation:

1. Examine the balanced chemical equation: N2 + 3H2 → 2NH3.

This equation shows that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.

2. Use the mole ratio from the balanced equation to find the number of moles of hydrogen needed.

Since the mole ratio of nitrogen to hydrogen is 1:3, for every one mole of nitrogen, we need 3 moles of hydrogen to react completely.

3. Set up a proportion to find the number of moles of hydrogen.

Let x be the number of moles of hydrogen needed. The proportion will look as follows:

1 mole of nitrogen / 3 moles of hydrogen = 2.6 moles of nitrogen / x moles of hydrogen

4. Solve for x.

Taking the cross-products of the proportion, we have:

1 * x = 3 * 2.6
x = 7.8

Therefore, 7.8 moles of hydrogen are needed to completely react with 2.6 moles of nitrogen.
