Q: The burning of high-sulfur fuels has been shown to cause
The burning of high-sulfur fuels has been shown to cause the phenomenon of “acid rain.” When a high-sulfur fuel is burned, the sulfur is converted to sulfur dioxide (SO2) and sulfur trioxide (SO3). Wh...
See AnswerQ: The Group 2 metals (Ba, Ca, Sr) can
The Group 2 metals (Ba, Ca, Sr) can be produced in the elemental state by the reaction of their oxides with aluminum metal at high temperatures, also producing solid aluminum oxide as a by-product. Wr...
See AnswerQ: There are fears that the protective ozone layer around the earth is
There are fears that the protective ozone layer around the earth is being depleted. Ozone, O3, is produced by the interaction of ordinary oxygen gas in the atmosphere with ultraviolet light and lightn...

See AnswerQ: When elemental phosphorus, P4, burns in oxygen gas, it
When elemental phosphorus, P4, burns in oxygen gas, it produces an intensely bright light, a great deal of heat, and massive clouds of white solid phosphorus(V) oxide (P2O5) product. Given these prope...
See AnswerQ: Calcium oxide is sometimes very challenging to store in the chemistry laboratory
Calcium oxide is sometimes very challenging to store in the chemistry laboratory. This compound reacts with moisture in the air and is converted to calcium hydroxide. If a bottle of calcium oxide is l...
See AnswerQ: Although they were formerly called the inert gases, the heavier elements
Although they were formerly called the inert gases, the heavier elements of Group 8 do form relatively stable compounds. For example, at high temperatures in the presence of an appropriate catalyst, x...
See AnswerQ: The element tin often occurs in nature as the oxide, SnO2
The element tin often occurs in nature as the oxide, SnO2. To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). This produces pure molten tin, with the ca...
