Sketch the structural formulas of two hydro- carbon molecules that are isomers. Be sure the
Cand H atoms form the correct numbers of
bonds. What are the molecular formulas of the
molecules? What is identical about the mole-
cules? How do the molecules differ?

1 and 6 for apex

i need an image of the diagram

a. by using fur or clothes to trap heat energy near the body

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
