Question

Carbon burnt in two ways i.e. in one way oxygen gas is supplied in sufficient
amount and another way in which oxygen is supplied in limited amount.:
Which of the law to be followed by this experiment:
(A) Law of multiple proportions (B) Law of constant proportions
(C) Law of conservation of mass (D) All of these​

Answer 1

Answer:(c)

Explanation: In a reaction it is always must for the law of conservation of mass to be obeyed.No matter what the reaction is there is the exception only on nuclear fission and nuclear fusion.Since the question says only carbon is burnt so it may be any hydrocarbon or carbon directly so which means we cant say about  the proportion in which it burns unless the value of o2 is specified.

Hope this helps.
