Assertion :The effects of charge exchange are usually only noticed when at least one of the surfaces has a high resistance to electrical flow. Reason: This is because the charges that transfer to or from the highly resistive surface are more or less trapped there for a long enough time for their effects to be observed.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Due to either one of surface being of a high resistance, the rate of transfer of charge is slowed down and thus it is observed.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica

Assertion: Be and Al have similar properties.

Reason: $B e^{2 +}$ and $A l^{3 +}$ have nearly the same charge/volume ratios and similar polarising power.

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.
