LAWS OF CHEMICAL COMBINATION consist of two laws:
Law of Conservation of Mass:
It states that matter can neither be created nor destroyed. eg: nuclear reaction.
Law of Definite Proportions:
It stated that a given compound always contains exactly the same proportion of elements by weight.
eg: ratio of 1:8 of hydrogen to oxygen in water.

Basically there are 5 laws of chemical combination.Two of them are-
1.Law of conservation of mass
This law says that mass can neither be created nor be destroyed.
EG.There is a glass of 10g it falls down and breaks into smaller fragments.If you measure the weight of all the fragments even of the smallest one you will get 10g only.neither less nor more
2.Law of constant proportion
This law states that a compound always contains it elements in a fixed ratio or mass.
EG.Taking example of water that is H2O.It contains atoms of hydrogen whose mass is 1 and two atoms make it 2.Mass of oxygen is 16.so it will be 2:16.simplifying it will be 1:8.So always a water molecule will be in ratio 1:8
