If carbon and oxygen combine in 3:8 proportion to form carbon dioxide. If we will add 15 g of carbon to 60g of oxygen , then how much carbon dioxide we will obtain???

ᴀɴꜱᴡᴇʀ :

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.

Answer 2

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

will be reacted with 3g of carbon (because carbon is the limiting reagent here ) to form 11g of CO

and 42 g of oxygen will remain unreacted.
