A Nissan brand car that runs on natural gas fuel was tested for combustion products and the following results were obtained on a molar basis: 2% CO, 8% CO2 and 6% O2. The fuel is composed of 50% CH4 and 50% C2H6 on a molar basis. If the products are cooled to the temperature of the reactants, it is asked to determine:
a) The balanced reaction equation, indicating the calculation basis.
b) The theoretical air percentage. %
c) The mass of H2O present in the products, in kg
d) The air / fuel ratio (kg air / kg fuel).
e) Gravimetric analysis of fuel (%)
