‘If 100 grams of calcium carbonate (whether in the form of marble or chalk) are decomposed completely, then 56 grams of calcium oxide and 44 grams of carbon dioxide are obtained’. Which law of chemical combination is illustrated by this statement?

Answer :

The above statement justifies the Law of constant proportions which was given by Joseph Proust in 1799. According to this law, “a chemical compound always contains same elements in definite proportion by mass and it does not depend on the source of compound.” This suggests that whatever be the source of water, it will always contain 1:8 ratio of Hydrogen and oxygen respectively.
