Question

Qno 5 Methane goes through combustion by comsuming Oxygen through the formula

CH₄ + 2O₂ ------>CO₂ + 2H₂ O

If inputs are CH₄ =1kg O₂ =4kg and N₂ =13.2kg Prove law of conversation

If CO₂ 2.75Kg ,H₂O=2.25Kg

Open in App

Solution

We are given the following equation
CH₄ + 2O₂ â†’ CO₂ + 2H₂O
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus, in a chemical reaction the total mass of the reactants is equal to the total mass of the products. We are given that 1kg of methane is reacting with 4kg of O₂ to form 2.75kg of CO₂ and 2.25kg of H₂O. Thus
total mass of reactants = mass of CH₄ + mass of O₂ = (1 + 4) kg = 5 kg
total mass of products = mass of CO₂ + mass of H₂O = (2.75 + 2.25) kg = 5 kg
Hence, we see that in the above reaction mass of reactants = mass of products
i.e. law of conservation of mass is satisfied here.
