Question

How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas?

Answer 1

4 moles of water are produced

Explanation:

• 4 moles of water are produced when 5 moles of hydrogen is reacted with 2 moles of oxygen gas
• The balanced equation given is when 2 moles of hydrogen reacts with 1 mole of oxygen and it forms 2 moles of water.
• The equation we have to solve is the 5 moles of hydrogen is reacting with 2 moles of oxygen gas, we can write the equation as $5H_{2} +2O_{2} --> 4H_{2} O + H_{2}$
• This is the balanced equation when 5 moles of hydrogen reacts with 2 moles of oxygen. The balanced equation means the number of hydrogen atoms and oxygen atoms on both sides would be equal in number.
