How does the law of conservation of mass apply this reaction mg + HCl - - H2 + mgcl2

A: equation needs to be balanced or if you were hydrogen atoms in the equation than magnesium or chlorine

B: the law of conservation of mass has already been applied there is an equal number of each element on both sides of the equation

C: only hydrogen needs to be a balance there are equal numbers of magnesium and chloride

D: hydrogen and chlorine need to be balanced there's an equal amount of magnesium on each side
