Q1. Given below are two statements:

Assertion (A):	Zinc is not a transition metal.
Reason (R):	Zinc has a full d¹⁰ configuration in its ground state as well as in its common oxidation states.

In light of the above statements, choose the correct answer from the options given below:

Both(A)and(R)are True and(R)is the correct explanation of(A)
Both(A)and(R)are True but(R)is not the correct explanation of(A)
(A)is True but(R)is False
(A)is False but(R)is True

Q2.

A gas that can readily decolorize an acidified KMnO₄ solution is:

SO₂
NO₂
P₂O₅
CO₂

Explanation:

HINT: SO₂ can decolorize acidified KMnO₄ solution.

Explanation:

SO₂ gas can readily reduces acidified KMnO₄ solution because KMnO₄ is an oxidising agent that easily oxidise SO₂.

$2 {MnO}_{4}^{-} +$ $5 {SO}_{2}$ $+$ $2 H_{2} O$ $\to 2 {Mn}^{2 +}$ $+$ $5 {SO}_{4}^{2 -}$ $+$ $4 H^{+}$

While other options such as NO₂ (strong oxidising agent), CO₂ (neither oxidising agent nor reducing agent cannot decolourise acidified KMnO₄ solution.
