Question

Consider the following reaction.
$C a C O_{3} (s)$ + $H_{2} O (l)$ + $C O_{2} (g)$ $\to$ $C a (H C O_{3})_{2} (a q)$

$\begin{matrix} Element & Number of atoms present \end{matrix}$
$\begin{matrix} Reactant side & Product side Calcium & 1 & 1 Carbon & 2 & Y Oxygen & X & 6 Hydrogen & 2 & 2 \end{matrix}$

Solution

From the equation: $C a C O_{3} (s)$ + $H_{2} O (l)$ + $C O_{2} (g)$ $\to$ $C a (H C O_{3})_{2} (a q)$

$\begin{matrix} Element & Number of atoms present \end{matrix}$
$\begin{matrix} Reactant side & Product side Calcium & 1 & 1 Carbon & 2 & (Y = 2) Oxygen & (X = 6) & 6 Hydrogen & 2 & 2 \end{matrix}$
Thus, the value of $X + Y = 6 + 2 = 8$
