Question

formation of water: 2H2 + 102 --> 2H20
How many moles of H2O can be produced from 7 moles of H2?




Help me please Answer or I’ll report

Answer 1

Answer:

It takes 7 mol H2 to produce 7 mol H2O

Explanation:

In 2H2O, there's 2 moles of H2 for every 1 mol O2.

So, if oxygen is limiting you'd only be able to produce 2 moles of H2O. I don't know if the question implies that, so it could also be that 7 mol H2 makes 7 mol H2O. Sorry for the confusion, I hope it helps a bit
