1.	Consider the following reaction. CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq) Element Number of atoms present Reactant sideProduct sideCalcium11Carbon2YOxygenX6Hydrogen22 Recognise X and Y. The value of X + Y is___.
Answer» Consider the following reaction. $C a C O_{3} (s)$ + $H_{2} O (l)$ + $C O_{2} (g)$ $\to$ $C a (H C O_{3})_{2} (a q)$ $\begin{matrix} Element & Number of atoms present \end{matrix}$ $\begin{matrix} Reactant side & Product side Calcium & 1 & 1 Carbon & 2 & Y Oxygen & X & 6 Hydrogen & 2 & 2 \end{matrix}$ Recognise $X$ and $Y$ . The value of $X + Y$ is___.
