Question

Match each observation to the law that it illustrates Law of definite proportions law of constant composition)Lw of multiple proportions Law of conservation of mass The C:O mass ratio of one The C:O mass ratio of a particular When 3 g of carbon reacts compound is exactly double that of another compound. compound is the same, regardless of the size or source of the sample. with 8g of oxygen, 11 g of carbon dioxide is produced. Burning 10 g of propane roduces twice as much carbon dioxide as burning 5 g of propane

Explanation / Answer

A/c to law of conservation of mass , mass of products is equal to the mass of the reactants .

So , 3g C with 8g O2 produce 11 g co2 is correct option .

2 . Law of definite composition - The C: O mass ratio of a particular compound is the same, regardless of the size and source of sample.

3. A/ c to law of multiple proportion, the weight of one element that combine with a fixed weight of other are in ratio of whole numbers. Hence 10 g of propane produce the twice as much Co2 as burning of 5 g propane.
