Question

2. 3 g of carbon combines with 8 g of O to form CO2. How many grams of O will combine with 12 g of Carbon:

Answer 1

Answer:

Explanation:

Carbon and oxygen combine in 3:8 ratio. So 11 g of carbon dioxide is formed. Hence, in the latter case too, only 8 g of O2 will be reacted with 3g of carbon (because carbon is the limiting reagent here ) to f

orm 11g of CO2 and 42 g of oxygen will remain unreacted

When 3 g of carbon is burnt in 8 g of oxygen, 11g of carbon dioxide is produced. What mass of carbon dioxide will be formed when 3 g of carbon is burnt in 50 g oxygen?

ANSWER

This is governed by the law of definite proportion. Carbon and oxygen combine in 3:8 ratio. So 11 g of carbon dioxide is formed.

Hence, in the latter case too, only 8 g of O
