When 3.0g of carbon is burnt in 8.00 g oxygen, 11.00g of carbon dioxide is produced. What mass of carbon dioxide will be formed when 3.00g of carbon is burnt in 50.00g of oxygen? Which law of chemical combination will govern your answer.

Text Solution

Verified by Experts

3.0g of carbon combines with 8.0 g of oxygen to give 11.0 of `Co_(2)`
If 3 g of carbon is burnt in 50 g of oxygen, then 3g of carbon will react with 8 gofoxygen. The remaining 42 gofoxygen will be left un-reactive.
In this case also, only 1lg of Co, will be formed. The above answer is governed by the law of constant proportions.
