Suppose the same mass of fuel was used in a fusion reaction and a fission reaction. About how many times more energy would be released by the fusion reaction?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

An observation that requires measurement is called quantitative observable or qualitative
