Answer:

the Law of multiple proportions

Explanation:

The law of multiple proportions states that, if two elements A and B combine to form more than one chemical compound, then the various masses of one of the elements A, which combines with a fixed mass of the element B are in simple multiple ratio.

This is demonstrated in the formation of nitrogen compounds such as NO and N2O when nitrogen combines with oxygen. This ratio is always constant.

34 atoms of carbon react with 22 molecules of hydrogen gas. How many molecules of methane will be formed &amp; what will be left
pychu [463]
Each carbon atom will react with 4 hydrogen atoms to form methane (C H_{4}) Since there are 2 hydrogen atoms in a hydrogen molecule (H_{2}) then each carbon atom will react with 2 hydrogen molecules. Since there are 22 hydrogen molecules half as many methane molecules will be formed, so 11. Then we can subtract 11 from 34 to find the number of carbon atoms left over.

So in summary, 11 methane molecules will be formed and there will be 23 carbon atoms left over.
