A scientist studies the following chemical equation for the production of water. 2H2+O2 = 2H2O what happens to the mass of the reactants during this chemical reaction

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

i think that the answer is c
