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.

Q. Assertion: The compressibility factor for

H_{2}

H e

(1 + \frac{P b}{R T})

Reason: The compressibility factor for

H e

can be derived from Van der Waal's equation.

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

{SiO}_{2}

present in iron ore is removed by

{CaCO}_{3}

CaO

formed by decomposition of

{CaCO}_{3}

{SiO}_{2}

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

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