these are the five laws which are said to be governing chemical reactions..........................................
1,law of conservation of mass; mass can neither be created nor be destroyed..(lovosiere)
2,law of definite combination;2 elements always combine in the same proportion by mass to form a same compound...(joseph prost)
3,law of multiple proportion;when 2 elements combine to form 2 different compounds,the masses of the element combined with the same mass of the other element will be in small whole number ratio..
4,gay lussac's law of gaseous volumes; gases always combine by th same volume to form the same compound given temperature nd pressure are same for all gases in the reaction...
5,avogadro's law; gases at same temperature nd pressure contains same no. of particles...
