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.
