Assertion :

Cattle breeds can be improved by super ovulation and embryo transplantation.

Reason: Semen of superior bulls is artificially inseminated into native cows.

Q. Assertion: The compressibility factor for $H_2$​ and $He$ is $(1+\frac{Pb}{RT})$
Reason: The compressibility factor for $H_2$​ and $He$ can be derived from Van der Waal's equation.

Q.

Assertion – The non-fusible impurities present in iron ore are removed by $CaC{O}_3$ .

Reason: $CaC{O}_3$ which decomposes into $CaO$ and $C{O}_2$. The $CaO$ formed reacts with $Si{O}_2$ to remove silica

Q.

ASSERTION: n-Pentane and n-Hexane belong to a homologous series.

REASON: n-Pentane and n-Hexane belong to the same class of hydrocarbons and they differ by a - $C{H}_2$ - group.

Q. Assertion: The impurities such as ${\text{SiO}}_2$ present in iron ore is removed by ${\text{CaCO}}_3$.

Reason: $\text{CaO}$ formed by decomposition of ${\text{CaCO}}_3$ reacts with ${\text{SiO}}_2$ to form slag.

Q.

Assertion (A) Order of the reaction can be zero or fractional.

Reason (R) We cannot determine order from balanced chemical equation.

(a) Both assertion and reason are correct and the reason is correct explanation of assertion
(b) Both assertion and reason are correct, but reason does not explain assertion.
(c) Assertion is correct, but reason is incorrect
(d) Both assertion and reason are incorrect
(e) Assertion is incorrect but reason is correct.
