Classify the following type of stoichiometry problem: How many grams of aluminum must react with an excess volume of nitric acid to yield 0.500 g of aluminum nitrate?
A) mass-mass problem
B) mass-volume problem
C) volume-volume problem
D) mole-mole problem
E) none of the above

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
