Detailed explanation-2: -A coefficient multiplies the number of atoms of each element indicated in a chemical formula. Thus, 2H2O represents four H atoms and two O atoms.
Detailed explanation-3: -Answer. it contains 2 atoms of hydrogen(H) and 1 atom of oxygen(O). So in total there are 3 atoms.
Detailed explanation-4: -The formula 2 H 2 O represents two molecules of. water. heavy water. hydrogen. .
Detailed explanation-5: -The molecular formula of hydrogen peroxide is H2O2; there are two H atoms and two O atoms in each molecule.
