Answer:
1) 2
This is a fact taht you have to remember
2) 4
Small trick : If you are asked to find out a pair which follows the law of multiple proportions,just look at the options -- the ones which have the same cation and same anion but combined in different ratios (like the one above) is your answer.
3) 1
Gases only combine in fixed whole number ratios. Judging by this statement, one part nitrogen will only combine with 3 parts hydrogen to form two parts ammonia. If you provide extra hydrogen(say four parts) , one part of hydrogen remains unreacted. This is ,in short, the law of definite proportions
4) 2
Well, there are some atoms which form many compound with the same atom of another kind.
Ex: NO2,N2O,N2O3 etc. As I mentioned above (in the 2nd point), these molecules have the same anions in this case. Therefore,the answer is law of multiple proportions.
5) 3
This follows the law of reciprocal proportions.
6) I am not so sure about the answer. Sorry,!
7) 2
Nuclear changes do not follow that law of conservation of mass. Remember this for now, you will learn a whole chapter on this later on!
Hope this helps :)
