Question

LIST-I contains compounds and LIST-II contains reaction

LIST I		LIST II
1	$H _2 O _2$	P	$Mg \left( HCO _3\right)_2+ Ca ( OH )_2 \rightarrow$
2	$Mg ( OH )_2$	Q	$BaO _2+ H _2 SO _4 \rightarrow$
3	$BaCl _2$	R	$Ca ( OH )_2+ MgCl _2$
4	$CaCO _3$	S	$BaO _2+ HCl \rightarrow$
		v	$Ca \left( HCO _3\right)_2+ Ca ( OH )_2 \rightarrow$

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

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

Answer 1

Answer: (D)

(P) $Mg \left( HCO _3\right)_2+2 Ca ( OH )_2 \rightarrow Mg ( OH )_2+2 CaCO _3+2 H _2 O$
(Q) $BaO _2+ H _2 SO _4 \rightarrow H _2 O _2+ BaSO _4$
(R) $Ca ( OH )_2+ MgCl _2 \rightarrow Mg ( OH )_2+ CaCl _2$
(S) $BaO _2+2 HCl \rightarrow BaCl _2+ H _2 O _2$
(T) $Ca \left( HCO _3\right)_2+ Ca ( OH )_2 \rightarrow 2 CaCO _3+2 H _2 O$
