... Note that this is an example of an ionic compound (see Module 3). The parentheses around (SO4) indicate that it is a polyatomic ion. Its actual formula is SO42-. Two Al3+ ions are required to balance the charge of the three SO42-. So, this formula also tells us that there are 2 Al3+ions and 3 SO42- ...

Since the enthalpy of adduct formation is least favorable with BF3, however, it is concluded that the loss in BX double-bond character upon rehybridization to form an adduct is greater with BF3 than in the other tri halides. From this we can conclude that the double-bond cha ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
