Answer #1

2H2 + O2 = 2 HO . 2 mole of H₂ reached 1 mole O needed 2 mols 40 produced. 2) 4 mol of My needed 2 mole on reacted 4 moles i

Here, moles are filled at missing place according to coefficient of balanced chemical equation.

For example in first reaction , mole of H2 and H2O must be same and moles of O2 will be half of mole of H2 or H2O.

In second reaction mole of every compound must be same.
