Question

A)state law of multiple proportion. B) name the chemical responsible for depletion of ozone layer​.

Answer 1

Explanation:

LAW OF MULTIPLE PROPORTION

According to this law, "when two elements combine to form two or more than two compounds, the weight of one of the element combines with fix weight of another element bears a simple multiple ratio to one another"

Illustrations

1. Cand O combines to form CO (carbon monoxide) and CO2 .The weight of oxygen which combines with fix wt of C(12) bears a simple multiple ratio to one another

compound. wt of C. wt of O carbon monoxide(CO) 12. 16

carbon dioxide(CO2) 12. 32

2. N and O combines to form the following compounds:

compound. wt of N. wt of O

1.nitrous oxide(N2O). 28. 16

2.nitric oxide (2NO). 28. 32

3.nitrogen trioxide. 28. 48

(N2O3)

4. nitrogen dioxide. 28. 64

(2NO2)

5. nitrogen pentoxide. 28. 80

(N2O5)

Chemical responsible for depletion of ozone layer

1. Methyl chloroform -- Finds its applications usually in industries for chemical processing etc.

2. Carbon Tetrachloride-- Normally used as a solvent.
