Question

2H₂ + O2 → 2H₂O

->
How many moles of water can be produced if 8 moles H₂ are used?
2 moles
16 moles
4 moles
8 moles

Answer 1

If 8 moles of H2 are used, 8 moles of water will be produced.

Step-by-step explanation:

First, we need to determine the mole ratio between H2 and H2O based on the balanced chemical equation. From the equation, we can see that 2 moles of H2 produce 2 moles of H2O.

Therefore, for every 1 mole of H2, we get 1 mole of H2O. If 8 moles of H2 are used, then 8 moles of H2O will be produced.

So, the correct answer is 8 moles of water.
