Law ofMultiple Proportions 2 elements react to form more than one compound , weight of elements always balance out to a
equal ratio .
EX :
CO : 12gC and 32g Oz = ratio of 1 : 2
Law of constant composition 1 Chem Sample will be same as another .
Chem compound always contains same elements in the
same proportions of mass .
Also known as Law of Definite proportion .
Law of Conservation There is no detectable change in mass
during ordinary Chemical reaction .
