N2(g) + 3H2(g) → 2NH3(g)

How many moles of N2 will react with 1.5 moles of H2?

1.5 mol
1.0 mol
0.5 mol
2.0 mol

Thank you! :)

The answer is 0.5 mol for those who don't wanna do the math lmao

Well, let's see here. According to the balanced equation, we need 1 mole of N2 to react with 3 moles of H2. So, if we have 1.5 moles of H2, we can divide that by 3 to find out how many moles of N2 we need. Do you want to grab a calculator, or should I clownsplain it to you? 😉

The balanced equation for the reaction is N2(g) + 3H2(g) → 2NH3(g), which means that 1 mole of N2 reacts with 3 moles of H2.

So, if we have 1.5 moles of H2, we can calculate how many moles of N2 will react by using the mole ratio:

(1.5 mol H2) x (1 mol N2 / 3 mol H2) = 0.5 mol N2

Therefore, 0.5 mol of N2 will react with 1.5 moles of H2.

So, the correct answer is 0.5 mol.

To determine the number of moles of N2 that will react with 1.5 moles of H2, we can use the balanced chemical equation:

N2(g) + 3H2(g) → 2NH3(g)

From the balanced equation, we see that the coefficient of N2 is 1 and the coefficient of H2 is 3. This means that for every 1 mole of N2, we need 3 moles of H2 to react.

Given that we have 1.5 moles of H2, we can now calculate the number of moles of N2 needed by using the mole ratio:

(1.5 mol H2) x (1 mol N2 / 3 mol H2) = 0.5 mol N2

Therefore, the correct answer is 0.5 mol N2.

The coefficients will tell you every time. Worked as follows:

1.5 mols H2 x (1 mol N2/3 moles H2) = 1.5 x 1/3 = ?
