What causes the ph of water to be 7.0?
(a) the amount of h+ ions is greater than the amount of oh- ions.
(b) the amount of h+ ions is less than the amount of oh- ions.
(c) the amount of h+ ions is equal to the amount of oh- ions.

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.

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?

Which of these expressions are correct variations of the combined gas law? p1v1t2 = p2v2t1 both
