Answers Calculate the pH at the equivalence point for the titration of 0.100 M methylamine ( CH 3 NH 2 ) with 0.100 M HCl . The K b of methylamine is 5.0 × 10 − 4 .

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
