Determine whether each of the following equations is balanced or not balanced: |
Part A 2H2S(aq)+H2SO3(aq)→3S(s)+3H2O(l) Part B NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l) Part C CaCO3(s)→3CaO(s)+CO2(g) Part D Na2O(s)+HCl(aq)→NaCl(aq)+H2O(l) |
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.
