. Law of Conservation of Mass
This law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of mass of reacting mixture and the products formed remains constant.
2. Law of Definite Proportions
It states that the proportion of elements by weight in a given compound will always remain exactly the same. In simple terms we can say that, irrespective of its source, origin or its quantity, the percent composition of elements by weight in a given compound will always remain the same.
3. Law of Multiple Proportions
This law states that if two elements combine to form more than one compound, the masses of these elements in the reaction are in the ratio of small whole numbers.
4. Gay Lussac’s Law of Gaseous Volumes
This law states that when gases are produced or combine in a chemical reaction, they do so in simple ratio by volume given that all the gases are at same temperature and pressure. This law can be considered as another form of law of definite proportions. The only difference between these two laws of chemical combination is that Gay Lussac’s Law is stated with respect to volume while law of definite proportions is stated with respect to mass.
5. Avogadro’s Law
It states that under same conditions of temperature and pressure, equal volume of all the gases contain equal number of molecules. This implies that 2 litres of hydrogen will have the same number of molecules as 2 litres of oxygen given that both the gases are at same temperature and pressure.

The Laws of Chemical Combination describe the basic principles obeyed by interacting atoms and molecules, interactions that can include many different combinations that happen in many different ways. This amazing diversity of interactions allows for an astounding variety of chemical reactions and compounds. Spontaneous chemical reactions happen constantly, shaping the world around us, while humans engineer specific reactions to our benefit and attempt to curb reactions that hurt us. Though chemical reactions can be as complex as they are numerous, they are all fundamentally governed by these same guiding Laws of Chemical Combination, which lay the groundwork for analysis of chemical reactions. They give a mathematical formulation and allow predictability given initial conditions. They are the launch pad from which we jump off to creating all sorts of wild compounds and phenomena. And while chemistry is still difficult and intricate, with the Laws of Chemical Combination on our side, we can begin to make some headway
