2) which of the following is a crystalline solid
A) diamond. . B) glass. C) rubber. D ) all of these

Answer 1

please follow

Explanation:

and the answer is b

Answer 2

1) Rate of reaction of any substance depends on (A) active mass.

- Actually, Rate of a reaction depends upon the concentration of reactants.

- Active mass denotes the concentration of substance.

- Thus, rate of reaction of any substance depends upon its active mass.

- Hence option (A) is the correct answer.

2) The crystalline solid among the following is (A) diamond

- Glass and rubber both are amorphous solids while diamond is a crystalline solid.

- Hence option (A) is the correct answer.
