Question

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

$\begin{matrix} Element & Number of atoms present \end{matrix}$
$\begin{matrix} Reactant side & Product side Calcium & 1 & 1 Carbon & 2 & Y Oxygen & X & 6 Hydrogen & 2 & 2 \end{matrix}$
Recognise $X$ and $Y$ . The value of $X + Y$ is___.

Open in App

Solution

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

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