Question

what are the laws of chemical combination​

Answer 1

Explanation:

Laws of Chemical Combination. It states that matter can neither be created nor destroyed. It stated that a given compound always contains exactly the same proportion of elements by weight.

Answer 2

Answer:

In chemistry, the laws of chemical combination are as follows :

• Mass can neither be created nor be destroyed that is also known as law of conservation of mass.

• After complete reaction, Mass of reactant = Mass of products.

• And in an incomplete reaction, mass of reactants = mass of products formed + mass of non-reacted reactant.

Note : Reactant are the elements or compounds that goes under reaction whereas the substance formed after reaction is known as product.

Also, energy is released and absorbed only by making and breaking of bonds. When bonds are made energy is evolved and when bonds break the energy is absorbed.
