I am having one doubt in these questions ...
When 3.0 g of carbon is burnt in 8.00 g oxygen, 11.00 g of carbon dioxide is produced. What mass of carbon dioxide will be formed when 3.00 g of carbon is burnt in 50.00 g of oxygen ? Which law of chemical combination will govern your answer?
and the second question is
When 5g of calcium is burnt in 2g of oxygen then 7g of calcium is produced . what mass of calcium oxide will be provided when 5g of calcium is burnt in 20g of oxygen ? which law of chemical combination will govern your answer?
I am puzzled because these question can govern both the laws of chemical combination. But in some book only one is written....plzzzzzzzz help me ....!
