Question

LIST-I contains compounds and LIST-II contains reaction

LIST I		LIST II
1	$H_2{O}_2$	P	$Mg{\left(HC{O}_3\right)}_2+Ca(OH{)}_2\to$
2	$Mg(OH{)}_2$	Q	$Ba{O}_2+H_{2}S{O}_4\to$
3	$BaC{l}_2$	R	$Ca(OH{)}_2+MgC{l}_2$
4	$CaC{O}_3$	S	$Ba{O}_2+HCl\to$
		v	$Ca{\left(HC{O}_3\right)}_2+Ca(OH{)}_2\to$

Match each compound in LIST - I with its formation reaction(s) in LIST-II, and choose the correct option

• A. $I\to Q$; II $\to$ P; III $\to$ S; IV $\to$ R
• B. I $\to$ T; II $\to$ P; III $\to$ Q; IV $\to$ R
• C. I $\to$ T; II $\to$ R; III $\to$ Q; IV $\to$ P
• D. I $\to$ Q; II $\to$ R; III $\to$ S; IV $\to$ P

Answer 1

Answer: (D)

(P) $Mg{\left(HC{O}_3\right)}_2+2Ca(OH{)}_2\to Mg(OH{)}_2+2CaC{O}_3+2H_{2}O$
(Q) $Ba{O}_2+H_{2}S{O}_4\to H_2{O}_2+BaS{O}_4$
(R) $Ca(OH{)}_2+MgC{l}_2\to Mg(OH{)}_2+CaC{l}_2$
(S) $Ba{O}_2+2HCl\to BaC{l}_2+H_2{O}_2$
(T) $Ca{\left(HC{O}_3\right)}_2+Ca(OH{)}_2\to 2CaC{O}_3+2H_{2}O$
