The formula of soap is RCOONa where R is a long hydrocarbon chain.
a)
There is no reaction between soap and NaCl. Hence, there is no equation.
b)
2RCOONa(aq) + MgCl₂(aq) → (RCOO)₂Mg(s) + 2NaCl(aq)
c)
3RCOONa(aq) + FeCl₃(aq) → (RCOO)₃Fe(s) + 3NaCl(aq)
d)
RCOONa(aq) + HCl(aq) → RCOOH(s) + NaCl(aq)
a)
There is no reaction between soap and NaCl. Hence, there is no equation.
b)
2RCOONa(aq) + MgCl₂(aq) → (RCOO)₂Mg(s) + 2NaCl(aq)
c)
3RCOONa(aq) + FeCl₃(aq) → (RCOO)₃Fe(s) + 3NaCl(aq)
d)
RCOONa(aq) + HCl(aq) → RCOOH(s) + NaCl(aq)

I see no reason to suppose soap solution reacts with any of those salts.

When you write an equation for a chemical reaction, the two sides of the equation should balance — you need the same number of each kind of element on both sides. If you carry out a chemical reaction and carefully sum up the masses of all the reactants, and then compare the sum to the sum of the masses of all the products, you see that they’re the same.
