Law of chemical combination
1) law of conservation of mass
it states that matter can neither be created nor destroyed
It was given by Antoine lavoisier
2) law of Definite proportions
it states that in a given compound always contains exactly the same proportions of elements by mass.
3) law of multiple proportions
according to this law if two elements can combine to form more than one compound the mass of an element that combine with a fixed mass of other elements are in the same ratio of small whole number
4) gay lussac's law of gaseous volumes
When gases combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same temperature and pressure.
5) Avogadro law
It states that equal volumes of gases at the same temperature and pressure should contain equal number of molecules.
6) Dalton's atomic theory
matter consists of indivisible atom
all the items of a given element have identical properties including identical mass atom of different elements differ in mass
compounds are formed when atoms of different elements combine in a fixed ratio
chemical reaction involved recognisation of atoms these are neither created nor destroyed in a chemical reaction.
