Answer: The correct option is d.
Explanation: Antoine Lavoisier is a french scientist who discovered the role of oxygen in the process of combustion and respiration.
He was famous for the law of conservation of mass.
This law states that the total mass the reactant will equal to the total mass of the products in a chemical reaction.
For example: Combustion of methane

Mass of the reactants = ![[12+4(1)]+[2(32)]=80g/mol](https://tex.z-dn.net/?f=%5B12%2B4%281%29%5D%2B%5B2%2832%29%5D%3D80g%2Fmol)
Mass of the products = ![[12+2(16)]+2[2(1)+16]=80g/mol](https://tex.z-dn.net/?f=%5B12%2B2%2816%29%5D%2B2%5B2%281%29%2B16%5D%3D80g%2Fmol)
Hence, every chemical reaction will follow law of conservation of mass.
When carbon is burned in air carbon iv oxide gas is formed.
C (s) + O2 (g) = CO2(g) ΔH = - 393.5 kj/mol
The enthalpy change of the reaction is -393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.
Thus, 1 mole = -393.5 j , then for 480 kj
= 480 × 1/393.5
= 1.2198 moles
1 mole of carbon iv oxide is equal to 44 g
thus, 1.2198 moles will be 1.2198 × 44 = 53.6712 g of CO2
