Question

define all threeee type of law of chemical combination??? ​

Answer 1

Explanation:

LAWS OF CHEMICAL COMBINATIONS:

Law of Conservation of Mass

It states that matter can neither be created nor destroyed.

Law of Definite Proportions

It stated that a given compound always contains exactly the same proportion of elements by weight.

Example : Oxygen and hydrogen in water always bear ratio of 16:2 or 8:1 by mass

Law of Multiple Proportions

According to this law, if two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole numbers.

Example

Hydrogen + Oxygen → Water

2g 16g 18g

Hydrogen + Oxygen → Hydrogen Peroxide

2g 32g 34g

Here, the masses of oxygen (i.e. 16 g and 32 g) which combine with a fixed mass of hydrogen (2g) bear a simple ratio, i.e. 16:32 or 1: 2.
