I WANT ALL THE ANSWER CORRECTLY! SHOW ALL THE CALCULATION USING HANDWRITING AND DONT CHEAT! PLEASE DONT WAST MY QUESTION!

Volumetric analysis of natural gas shows the following: 70%CH4,10%H2,15%N2,2%O2 and 3%CO2. This gas enters a combustion chamber at 25C and is burned with 25% excess air that enters the combustion chamber at 25C. The airflow rate is 0.67kg/min. An analysis of the combustion gases found that all hydrogen in the fuel burns to H2O but 85% of the carbon burns to CO2 and the remaining 15% produces CO. If the exit temperature of the combustion gases is 1000K, analyze the combustion process by determining the following: i) the balanced equation for stoichiometric combustion, ii) the balanced equation for actual combustion, iii) the actual air-fuel ratio for this combustion ( kg of air/ kg of fuel, iv) the fuel flow rate (kg/s), v) the enthalpy for the reactants (kJ/kMol of fuel), vi) the enthalpy for the products ( kJ/kMol of fuel), and vii) the rate of heat transfer from the combustion process (kW)
