The balanced equation shows the formation of water. 2 cap h sub 2 plus cap o sub 2 ce bond right arrow 2 cap h sub 2 cap o How many moles of oxygen open paren cap o sub 2 close paren are required to completely react with 27 point 4 mol of cap h sub 2 ?
The balanced equation shows that 2 mol of H₂ react with 1 mol of O₂. So 27.4 mol H₂ requires 27.4 ÷ 2 = 13.7 mol O₂, which is choice B, 13.7 mol.
