Read the following descriptions of physical or chemical changes and predict whether the change will be spontaneous, if you can. a) A gas condenses to a liquid, releasing heat is [predicta] b) A solid substance dissolves in water, releasing heat as it does so is [predictb] c) During an endothermic chemical reaction, four moles of gaseous reactants are turned into two moles of gaseous products is [predictc]

When 50.0 mL of 0.25 M methanoic acid, HCOOH, Ka = 1.8 × 10−4 is combined with 50.0 mL of 0.25 M hydrazine, H2NNH2, Kb = 1.3 × 10−6, the resulting solution is:
