The model below shows the equation that represents how hydrogen and oxygen combine to form water. 2H2 + O2 → 2H2O Read each statement below and select all that apply to the equation. The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product. The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product. The law of conservation of matter is not applied in this equation. The law of conservation of matter is not applied in this equation. The mass of the reactants is equal to the mass of the products in the reaction. The mass of the reactants is equal to the mass of the products in the reaction. The total number of each type of atom is conserved in the equation.
