$\begin{array}{cccc}& \text{Reaction Names}& & \text{Reactions}\\ \text{i}& \text{Displacement reaction}& & {\text{A. CaO + O}}_2\to {\text{2Ca(OH)}}_2\\ \text{ii}& \text{Decomposition Reaction}& & {\text{B. Fe + Pb(NO}}_3{)}_2\to {\text{Fe(NO}}_3{)}_2\text{+ Pb}\\ \text{iii}& \text{Redox Reaction}& & {\text{C. MgCl}}_2{\text{+ Ca(OH)}}_2\to {\text{Mg(OH)}}_2{\text{+ CaCl}}_2\\ \text{iv}& \text{Combination Reaction}& & {\text{D. KClO}}_3\to {\text{2KCl + 3O}}_2\\ \text{v}& \text{Double Displacement Reaction}& & {\text{E. CO}}_2{\text{+ H}}_2\to {\text{2CO + H}}_2\text{O}\end{array}$

• A. B, E, F, A and C
• B. B, F, E, A and C
• C. A, E, F, B and C
• D. A, F, E, B and C

Answer 1

The correct option is B

B, F, E, A and C

$\begin{array}{ccc}\text{S.No.}& \text{Reaction Names}& \text{Reactions}\\ \text{i}& \text{Displacement Reaction (element displacing other element from its compound)}& {\text{B. Fe + Pb(NO}}_3{)}_2\to {\text{Fe(NO}}_3{)}_2\text{+ Pb}\\ \text{ii}& \text{Decomposition Reaction (single product decomposing into two or more than two products)}& {\text{D. KClO}}_3\to {\text{2KCl + 3O}}_2\\ \text{iii}& \text{Redox Reaction (both oxidising and reducing)}& {\text{E. CO}}_2{\text{+ H}}_2\to {\text{2CO + H}}_2\text{O}\\ \text{iv}& \text{Combination Reaction (two reactants combine to give a single product)}& {\text{A. CaO + O}}_2\to {\text{2Ca(OH)}}_2\\ \text{v}& \text{Double Displacement Reaction (exchange of ions between reactions)}& {\text{C. MgCl}}_2{\text{+ Ca(OH)}}_2\to {\text{Mg(OH)}}_2{\text{+ CaCl}}_2\end{array}$
