Distilled water is touched by man so it would probably be close to 300 degrees farenheit.......maybe.
If the trend is linear, that is boiling point increases by a constant amount for each additional saturated carbon, the boiling point of octane would be 69*2 because you are adding two saturated carbons. So the predicted boiling point is 138C, which is very close to the literature value
hooc are carboxyl groups
your r or amino groups are those unique structures which have different atoms in them. your nh2 groups are your hydrogen atoms
The harmonic law would suggest that Neptune will take a longer amount of time to orbit the sun than Mercury. That's what I think anyways
