Q140CP - Chemistry: Molecular Nature Of Matter And Change

Question

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?

                           

Step-by-Step Solution

Answer

 

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

Step 1: Law of definite composition

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

Step 2: Solution Explanation

From the given,

                    

                                 

The law of definite composition 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. is shown here, as the atoms are combining in a fixed ratio of 2:1.
