Identify the compound $X$ on the basis of the reactions given below. Also,write the name and chemical formulae of $A$,$B$ and $C$.

(N/A) Based on the given reactions:
$1$. $X + Zn \rightarrow A + H_2(g)$: $A$ base reacts with zinc to produce hydrogen gas. Thus,$X$ is a base,$NaOH$.
$2$. $X + HCl \rightarrow B + H_2O$: $A$ base reacts with an acid to form salt and water (neutralization). Thus,$B$ is $NaCl$.
$3$. $X + CH_3COOH \rightarrow C + H_2O$: $A$ base reacts with acetic acid to form salt and water. Thus,$C$ is $CH_3COONa$.
Final identifications:
$X = NaOH$ (Sodium hydroxide)
$A = Na_2ZnO_2$ (Sodium zincate)
$B = NaCl$ (Sodium chloride)
$C = CH_3COONa$ (Sodium acetate)
