Copy the following and write the names of the laws and their simple definitions in the space provided.

● Box-1: Law Of Multiple Proportions:

This law states that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

● Box-2: Law of Conservation of Mass:

This law states that the mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.

According to the law of conservation of mass, the total mass of the reaction in a chemical reaction must equal the mass of the reactants.

● Box-3: Law of constant Proportions:

The law of constant composition says that, in any particular chemical compound, all samples of that compound will be made up of the same elements in the same proportion or ratio.

● Box-4: Law of Reciprocal proportions:

This law states that if two different elements combine separately with the same weight of a third element, the ratio of the masses in which they do so are either the same or a simple multiple of the mass ratio in which they combine.

● Box-5: Gay Lussac’s Law of Gaseous volumes:

This law states that the ratio between the volumes of the reactant gases and the gaseous products can be expressed in simple whole numbers. 2 molecules of hydrogen + 1 molecule of oxygen = 2 molecules of water.
