Correct answer is (a) 12 g of carbon combines with 32 g of oxygen to form 44 g of CO2

Q. Which of the following is the best example of law of conservation of mass?

$12 g$ of carbon combines with $32 g$ of oxygen to form $44 g$ of $C O_{2}$

When $12 g$ of carbon is heated in a vacuum there is no change in mass

A sample of air increases in volume when heated at constant pressure but its mass remains unaltered

The weight of a piece of platinum is the same before and after heating in air

Correct answer is (a) $12 g$ of carbon combines with $32 g$ of oxygen to form $44 g$ of $C O_{2}$
