If a reaction equation is balanced, then select all that apply. it will follow the law of conservation of mass there will be coefficients written in front of the formulas the mass of products will be equal to the mass of the reactants the mass of the products will be greater than the mass of the reactants

What changes occur in the reaction indicated by the equation? check all that apply. the hydrogen nucleus loses protons. the oxygen nucleus gains protons. the bond in h2 is broken, and new bonds are formed between hydrogen and oxygen atoms. each electron associated with a hydrogen atom is shared with an oxygen atom.
