The combustion of ethene, C2H4, is an exothermic reaction. Use the information below to determine the amount of energy given off when 2.3 moles of ethene is combusted. C2H4 + 3 O2 2 CO2 + H2OH= - 1390 kJ

In any energy conversion, some of the energy is lost to the environment as question 5 options: electrical energy potential energy sound energy thermal energy
