Question

Define any three laws of chemical combination.​

Answer 1

There are three major foundational of chemistry in terms of chemical and nuclear reactions: Law of the Conservation of Mass (mass before reaction has to equal mass after reaction) Law of Constant Proportions (the ratio mass for the same compound is constant)

Answer 2

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

LAWS OF CHEMICAL COMBINATIONS :

⏭️ Law of Conservation of Mass:

This law was given by Lavoisier. According to this law mass can neither be created nor can be destroyed but can be changed from one form to another form.

Total mass of reactants = Total mass of products.

⏭️ Law of Constant Proportion :

This law was given by Proust. According to this law, a compound may be obtain from different sources but the ratio of each component remains same that is, it doesn't depend on the method of its preparation or the source from which it has been obtained.

⏭️ Law of Multiple Proportion :

This law was given by Dalton. According to this law, if two elements combine to form more than one compound than the different masses of one element combines with fixed mass of the other element forms a simple ratio to one another.
