Some Basic Concepts Of Chemistry Question 68

Question: 20 g of $C a C O_{3}$ on heating gave 8.8 g of $C O_{2}$ and 11.2 g of CaO. This is in accordance with

Options:

A) The law of conservation of mass.

B) The law of constant composition.

C) The law of reciprocal proportion.

D) None of these

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $\underset{20 g}{C a C O_{3}}, \to \underset{8.8 g}{C a O}, + \underset{11.2 g}{C O_{2}},$ mass of reactant = mass of products = 20g. Hence the law of conservation of mass is obeyed.
