ANSWER

2H

+O

2

→2H

2

O

10 g of hydrogen (molar mass 2 g/mol) =

2 g/mol

10 g

= 5 mol

64 of oxygen (molar mass 32 g/mol) =

32 g/mol

64 g

= 2 mol

As per the balanced chemical equation, 1 mole of oxygen will react with 2 moles of hydrogen to form 2 moles of water.

2 moles of oxygen will react with 2×2=4 moles of hydrogen to form 4 moles of water.

Here, oxygen is the limiting reagent and hydrogen is the excess reagent
