Question

when 3.0g of carbon is burnt in 8.0g oxygen,11.0g of carbon dioxide is produced.what mass of carbon dioxide will be formed when 3.0g of carbon is burnt in 5.0g of oxygen?which law of chemical combination will govern

Answer 1

8.0g of CO2 will be formed this is law of conservation of mass

Answer 2

Explanation:

It is given that 3.0 g of carbon is burnt with 8 g of oxygen to produce 11.0 g of CO2. Consequently 11.0 g of carbon dioxide will be formed when 3.0 g of C is burnt in 50 g of oxygen consuming 8 g of oxygen, leaving behind 50 �V 8 = 42 g of 02. The answer governs the law of constant proportion.
