| Chemistry Question? need help please>>>?
A mass of 1.00 kg of gas will generally produce 43.7 MJ of energy. If one particular car can travel 700 km on one tank (50 L or 37 g) of gas, the car produces 1616.9 kJ of energy. a)If only 20% of the energy produced by burning the gas is used to move the car forward, how much energy does it take to move the car 700 km?      |
