One of the products of combustion is water. Why doesn't this water extinguish the combustion?
A) While areas of combustion are being extinguished, new areas are combusting.
B) Combustion only produces micro amounts of water.
C) The chemical combustion reaction is happening too fast for the water to have an effect on the fire.
D) This water is in the gaseous phase and merely floats away from the fire.
Question 2
The oxidation of iron to rust is a problem structural engineers need to be concerned about, but the oxidation of aluminum to aluminum oxide is not so much of a problem. Why?
A) Since aluminum is so light and inexpensive, it is easily replaced when corroded.
B) Aluminum oxide is insoluble in water and thus forms a protective coating that prevents continued oxidation of the aluminum.
C) Aluminum oxide is even stronger than aluminum.
D) The oxidation of aluminum is a very slow reaction, taking hundreds of years before any structural changes are noticed.
