A gobar gas plant produces methane and supplies to the families. If a family requires 15000 kJ of energy per day, how many days will the quota of 20 kg will last (Delta_(c) H of CH_(4) = -1665 kJ mol^(-1) ).

A cylinder of gas supplied by Bharat Petroleum is assumed to contain 14 kg of butance. If a normal family requires 20,000 kJ of energy per day for cooking, butane gas in the cylinder lasts (Delta_(C ) H^(@) of C_(4) H_(10) = - 2658 kJ mol^(-1))

a. A cylinder of gas is assumed to contain 11.2 kg of butane. If a normal family needs 20000kJ of energy per day for cooking, how long will the cylinder last? Given that the heat of combustion of butane is 2658 kJ mol^(-1) . b. If the air supply of the burner is insufficient (i.e. you have a yellow instead of a blue flame), a portion of the gas escape without combustion. Assuming that 33% of the gas is wasted due to this inefficiency, how long would the cylinder last?

In a gobar gas plant, gobar gas is formed by bacterial fermentation of animal refuse. It mainly contains methane and its heat of combustion is -899kJ mol^(-1) according to followinf equation: CH_(4) +2O_(2) rarr CO_(2)+2H_(2)O , DeltaH =- 809 kJ How much gobar gas would have to be produced per day for a small village of 50 families, it it is assumed that each family requires 20000 kJ of enegry per day? The methane content in gobar gas is 80% by mass.

A cylinder of gas is assumed to contains 11.2 kg of butane. If a normal family needs 20, 000 kJ of energy per day for cooking, how long will the cylinder last if the enthalpy of conbustion, DeltaH=-2658" kJ/mole" for butane.
