Most car engines run on petrol, which is usually treated as octane (c8h18). a top fuel dragster’s fuel includes nitromethane (ch3no2), which has complete combustion products of carbon dioxide, nitrogen and water. the two fuels have calorific values of 43.7 mj/kg and 11.3 mj/kg respectively. a common fuel in drag racing is a mixture of 10% octane and 90% nitromethane (molar fractions). (i) write the combustion equation for the dragster fuel, including 20% excess air. (ii) if an engine running on octane produces 100 kw when running with 20% excess air, what power would it produce using the 10/90 fuel mix? assume that the mechanical and volumetric efficiencies of the engine remain the same

Acompound contains only carbon, hydrogen, nitrogen, and oxygen. combustion of 0.157 g of the compound produced 0.213 g of co2 and 0.0310 g of h2o. in an- other experiment, 0.103 g of the compound produced 0.0230 g of nh3. what is the empirical formula of the compound? hint: combustion involves reacting with ex- cess o2. assume that all the carbon ends up in co2 and all the hydrogen ends up in h2o. also assume that all the nitrogen ends up in the nh3 in the second experiment.
