The following choices..:
A. Lipids have more hydrogen relative to oxygen than do carbohydrates.
B. Lipids and carbohydrates have different functions.
C. Lipids don't dissolve easily in water, while carbohydrates do.
D. Lipids do not chain together to form larger molecules, while carbohydrates do.
E. All of the above are correct
The answer would be E, all of the above
First solve the moles of oxgen present in the compound
mol O = 6.93 g O ( 1 mol O / 16 g O )
mol O = 0.43 mol H
then solve the moles of hydrogen present
mol H = ( 7.36 - 6.93) g H ( 1 mol H / 1 g H)
mol H = 0.43 mol H
so the O and H are in the same mole content so the molecular formula would be OH, but the molar mass will not satisfy. so the answer would be
H2O2

What causes a substance to change states of matter?
Energy causes a substance to change states of matter. A matter needs energy to melt, evaporate, boil. Remember: Energy has a sudden change, but the temperature remains absolutely the same. An example of a change in energy is when ice is melting.
Hope I helped (:
Have a great day!
