What is the global significance of methane gas? Correct Answer Highest calorific value

The calorific value of methane gas is 55mJ/Kg which can be used as a fuel and natural gas has the lowest calorific value, eutrophication leads to algal blooms which deteriorates the health of aquatic life, BOD determines the amount of oxygen which is consumed by the organic matter present in water. Eutrophication is harmful to aquatic life.

In a newly developed innovative idea brought up by CSIR in India, gas turbine exhaust gas are being utilized to convert feedwater into steam. Certain data of the experiment are as follows: mass flow rate of exhaust gas = 40 kg/hr, enthalpy of exhaust gas at the time of their exit from gas turbine is 600 kJ/kg, steam turbine output as measured by brake dynamometer = 60 hp-sec, thermal efficiency of steam power plant is 0.25, efficiency of exhaust gas in converting feedwater into steam is taken as 50%. Find the enthalpy of exhaust gas remaining after they generate steam from feedwater?
One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH4 + 2O2 → CO2 + 2H2O. Both the reactants and products are in gas phase. ΔH°298 = -730 kJ/mole of methane. Mole fraction of water vapour in the product gases is about
