5. Classify: Astronomers classify the eight planets in our solar system into two groups: terrestrial planets and gas giants. Terrestrial planets have rocky surfaces, while gas giants
are composed mainly of gas. Based on your data, classify each planet as a terrestrial planet
or a gas giant. (Hint: Look at the density of each planet.)

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.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
