Question

Match the following reactions with their corresponding unbalanced equations:

• A. A – (iii); B – (ii); C – (iv); D – (i)
• B. A – (i); B – (iv); C – (ii); D – (iii)
• C. A – (i); B – (ii); C – (iii); D – (iv)
• D. A – (iii); B – (iv); C – (ii); D – (i)

Hint:

For matching reactions, identify the reaction type first (combination, decomposition, disproportionation, displacement) and then match with given equations.

Answer 1

The Correct Option is D

Step 1: List the types of reactions and equations.
- A: Combination reaction \(\rightarrow\) Mg + N2 → Mg3N2 (iii)
- B: Decomposition reaction \(\rightarrow\) KClO3 → KCl + O2 (iv)
- C: Disproportionation reaction \(\rightarrow\) Cl2 → Cl− + ClO3− (ii)
- D: Displacement reaction \(\rightarrow\) AgNO3 + CaCl2 → AgCl + Ca(NO3)2 (i)

Step 2: Match each type to the correct equation.
From step 1, we can directly match:
A → iii, B → iv, C → ii, D → i

Step 3: Conclusion.
Hence, the correct matching is \[ \boxed{\text{A – (iii); B – (iv); C – (ii); D – (i)}}. \]
