Solutions

Expert Solution

A) 2H2S(aq) + H2SO3(aq) ? 3S(s) + 3H2O(l) not balanced

number of atoms in reactant side is not equal to number of atoms in product side.

B) NaOH(aq) + HCl(aq) ? NaCl(aq) + H2O(l) balanced

number of atoms in reactant side is equal to number of atoms in product side.

C ) CaCO3(s) ? 3CaO(s) + CO2(g) balanced

number of atoms in reactant side is equal to number of atoms in product side.

D ) Na2O(s) + HCl(aq) ? NaCl(aq) + H2O(l) not balanced

number of atoms in reactant side is not equal to number of atoms in product side.
