Question

How much quantity of co2 reaches atmosphere when 1 kg of methane is burnt?

Answer 1

when methane is burnt in the presence of Oxygen, it gives carbon dioxide and water. reaction of methane with oxygen is ...

from reaction, it is clear that one mole of methane forms 1 mole of carbon dioxide.

we know, molar mass of methane = 16g/mol

and molar mass of carbon dioxide = 44g/mol

or, 16g of methane produces 44g of carbon dioxide.

or, 1kg of methane produces 44/16 × 1 kg = 2.75 Kg, of carbon dioxide.

hence, amount of CO2 reaches atmosphere when 1kg methane is burnt = 2.75kg
