Ozone (O3) and oxygen (O2) are
B) similar in reactivity.
D) liquids at room temperature.
Hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) are good substitutes for chlorofluorocarbons (CFCs) because
A) they are also greenhouse gases.
B) C-F bonds will react more easily with hydroxyl radicals, so they are broken down before they reach the stratosphere.
C) C-H bonds will react more easily with hydroxyl radicals, so they are broken down before they reach the stratosphere.
D) they are too heavy to reach the stratosphere.
C. C-H bonds will react more easily with hydroxyl radicals, so they are broken down before they reach the stratosphere.
Without the greenhouse effect,
A) the Earth would be much colder.
B) no precipitation would fall.
C) there would be no change of season.
D) more earthquakes would occur.
A. the Earth would be much older.
