Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off! ... https://www.youtube.com/watch?v=2h8XiqSnzaU Note: All Khan Academy content is available for free at (www.khanacademy.org)

The temperature conditions under which a process is thermodynamically favored (ΔG° is negative) can be predicted from the signs of ΔH° and ΔS°. When ΔH° is negative and ΔS° is positive, the process is favored at all temperatures. When ΔH° is positive and ΔS° is negative, the process is favored at no temperature. When ΔH° and ΔS° are both negative, the process is favored only at low temperatures. When ΔH° and ΔS° are both positive, the process is favored only at high temperatures.

Titrating a polyprotic acid with a strong base produces a pH curve with as many equivalence points as there are acidic protons on the acid. The pKₐ values for these protons can be estimated from the corresponding half-equivalence points on the curve, where pH = pKₐ.
