Question

N2 + 3 H2 --> 2 NH3

The balanced equation above indicates that if 2 moles of N2 react, then

2 moles of H2 will also react
3 moles of H2 will also react
4 moles of NH3 will be produced
2 moles of NH3 will be produced

Answer 1

According to the balanced chemical equation N2 + 3 H2 --> 2 NH3, for every 1 mole of N2 that reacts, 3 moles of H2 are required to react completely to form 2 moles of NH3. Therefore, if 2 moles of N2 react, then 6 moles of H2 will also react to form 4 moles of NH3.

So the correct answer is: 6 moles of H2 will also react, and 4 moles of NH3 will be produced.

Step-by-step explanation:

Answer 2

4 moles of NH3 will be produced

Step-by-step explanation:

The reaction expression is given as:

N₂ + 3H₂ → 2NH₃

We have to check that the equation of the reaction is balanced.

Then;

if 2 mole of N₂ reacts;

1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃

2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃

6mole of H₂ to produce 4 mole of NH₃
