Answer 1

There are many possible combinations of atoms

Step-by-step explanation:

This is based on the Law of Multiple Proportion. Two different elements can combine in different ratio to create multiple compounds. Let’s take the example of CO and CO₂. In carbon monoxide there is 1:1 ratio of C:O and in carbon dioxide the ration of C:O is 1:2. Because of the difference in combination ratios of the individual elements the two compounds have different physical and chemical property.

Answer 2

There are many possible combinations of atoms

Step-by-step explanation:

Atoms in the periodic table can combine in a myriad of ways – sometimes quoted to approximately 10^78 combinations. To understand the enormity, carbon (and its ability to form numbers combination with other elements) is the main element significant in the variations of organic life on earth.
