12. Ethanol is used as a fuel and is the main ingredient of alcohol. Calculate the amount of energy required to evaporate 2.5g of ethanol. See the values in the table at the end of this worksheet to solve this problem. Is energy absorbed or released?

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

i think the answer is tomato juice? not entirely sure though
