N2+3H2-> 2NH3 how many moles of hydrogen are needed to completely react with 2.6 moles of nitrogen?

Pls! Answer the questions

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.

Use the coefficients in the balanced equation.

2.6 mol N2 x (3 mols H2/1 mol N2) = 2.6 x 3/1 = ?
