Chapter 2: Q140CP (page 87)

The scenes below represent a mixture of two monatomic gases undergoing a reaction when heated. Which mass law(s) is(are) illustrated by this change?

Short Answer

Expert verified

The law of definite composition and law of conservation of mass, is illustrated here.

Step by step solution

01

Step 1:Law of definite composition

According to this law” the constituents of a pure compound are always mixed in set weight proportions”.

02

Step 2: Solution Explanation

From the given,

Thelaw of definite compositionis shown here, as the atoms are combining in a fixed ratio of 2:1. It also obeys law of conservation of mass as mass is not changing before and after the reaction as all the three scene contains same number of atoms of both gases.is shown here, as the atoms are combining in a fixed ratio of 2:1. It also obeys law of conservation of mass as mass is not changing before and after the reaction as all the three scene contains same number of atoms of both gases.
