2o) chen g be 30g of carbon ito burnt in 8.00 g oxygen, 11.00 g of carbon dioxide is produced. What mass of carbon dioxide will formed when 8.00 8 6 g of carbon is burnt in 50.00 oxygen & which law of chemical combination will govern your 2 2 anser ?
Ans:- when 3.00g of carbon is burnt in 50.00g of oxygen 11g of carbon dioxide will be formed. Because carbon and oxygen always as combine in ratio 3:8 to form carbon dioxide, Hence, only 8g of 50g of oxygen will react with 3g of carbon to form carbon dioxide.
My answer is governed by the law of constant proportion.

Answer:
As per the given condition, when 3.0 g of carbon is burnt in 8.00 g oxygen, 11.00 g of carbon dioxide is produced. Therefore, the law of conservation of mass is proved. Then, it also depicts that the carbon dioxide contains carbon and oxygen in a fixed ratio by mass, which is 3:8.
