Question

3. What is the greatest amount of H2O that can be made with 3.8 moles of H and 5 moles of

O? Which is the limiting reactant? Which reactant is in excess, and how many moles of it
are left over?

Answer 1

Answer: Hello!

first i believe we need a balanced equation to start...

i got 2H2 + 1O2 = 2H2O

This tells us that we need 2 moles of H2 for every 1 mole of O2 Since we only have 1 mole of H2 compared to the 5 moles of O2 hydrogen is the limiting reagent. For illustration, divide the balanced equation by 2 in order to get 1 mole of H2 If we start with 1.0 moles of H2 we'll produce 1.0 mole of H2O
