Solution

The correct option is D Both Assertion and Reason are incorrect
During aerobic respiration the final product of glycolysis i.e pyruvic acid is transported from the cytoplasm into mitochondria and undergoes oxidative decarboxylation reaction to form acetyl CoA . Aerobic respiration is the complete oxidation of glucose into $C O_{2}$ and $H_{2} O$ . There can be a net gain of 36 ATP molecules in aerobic respiration of one molecules of glucose.

Q. Assertion: The impurities such as

{SiO}_{2}

present in iron ore is removed by

{CaCO}_{3}

.

Reason:

CaO

formed by decomposition of

{CaCO}_{3}

reacts with

{SiO}_{2}

to form slag.

Assertion (A) All collision of reactant molecules lead to product formation.

Reason (R) Only those collisions in which molecules have correct orientation and sufficient kinetic energy lead to compound formation.

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

Lithium sulphate does not form alums.

Reason

$L i^{+}$ is too small to form a stable lattice required for double-salt/alum formation.
