Directions: Balance first the chemical equation below by multiplying the coeffícient to the number of atoms of each element. Then, multíply it by the atomic mass or weight. Please refer to the periodic table of elements in recording for the atomic mass or weight of the elements Involved. Besure that the total mass of the reactant is equal to the mass of the product. This is the balance equation: 2H2 02 2H20 H=4 H=4 O=2 O=2 H=4x1=D4 g/mol O=2x16=32 g/mol H=4x1=D4 g/mol O=2x16-32 g/mol 36 g/mol 36 g/mol
