Question

When 3g of carbon is burnt in 8g of oxygen, 11g of carbon dioxide is produced. What mass of carbon dioxide will be formed when 3g of carbon is burnt in 50g of oxygen? Which law of chemical combination will govern your answer

Answer 1

Explanation:

3.0 g of carbon combines with 8.0 g of oxygen to give 11.0 of carbon dioxide.If 3 g of carbon is burnt in 50 g of oxygen, then 3 g of carbon will react with 8 g of oxygen. The remaining 42 g of oxygen will be left un-reactive.

In this case also, only 11 g of carbon dioxide will be formed.

The above answer is governed by the law of constant proportions.
