Solution: Predict the sign of ΔS for each of the following: a) A piece of wax melting b) Silver chloride precipitating from solution c) Alcohol evaporating d) A solid explosive converting to a gas e) 2 K(s

Problem

Predict the sign of ΔS for each of the following:

a) A piece of wax melting

b) Silver chloride precipitating from solution

c) Alcohol evaporating

d) A solid explosive converting to a gas

e) 2 K(s) + F2 g) → 2 KF(s)

f) NH3(g) + HBr(g) → NH4Br(s)

g) NaClO3(s) → Na+(aq) + ClO3- (aq)
