Anybody explain me. Laws of conservation of mass, Law of constant praportion, Law multiple praportion.
Answers
1)The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed. Hence, the quantity of mass is conserved over time.
2)In chemistry, the law of definite proportion, sometimes called Proust's law or the law of definite composition, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.
3)"If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers."
hope it helps

Matter can neither be created nor be destroyed in a chemical reaction.
Total mass of reactants = Total mass of Products
Law of constant proportion:
A pure chemical compound always contains the same elements combined together in the same fixed ratio by mass.
e.g. We get water from different sources but whatever is the source, the ratio between the mass of the element remains same.
H2O
H2 => 2
O => 16
2:16 or 1:8
But this law is not applicable to isotopes.
Law of Multiple proportions :
When two elements combined to form more than one chemical compound, the masses of one of the elements that combine with the pics and mass of other element, bears a symbol ratio.
e.g. Hydrogen and oxygen combine to form H2 and H2O2
