Answer to Question #162326 in General Chemistry for Akinola

Question

In a gas plant, gobar gas is formed by bacterial fermentation of animal refuse mainly contains methane and it's heat of combustion is -809kj/mol. CH4 + CO2 – CO2 +2H20 ∆H=-809kj/mol. How much gobar gas will be produced per day for a small village of 50families if it's assumed that each family requires 20,000kj of energy per day. The methane content in gobar gas is 80% by mass

Answer 1

 ∆H=-809kj/mol. 

If each family consumes 20000kj of energy per day then;

50 families will there consume;

$50 × 20000$ =1000000kj

1000000/809=1236.36moles
