Question

1.

The propellent used to help launch the space shuttle in the solid-fuel boosters attached to the vehicle is 1.1 million pounds of ammonium perchlorate and powdered aluminum. The reaction generating the energy to blast the orbitor into space is:

3 NH₄ClO₄(s) + 3 Al(s) ---> Al₂O₃(s) + AlCl₃(s) + 3 NO(g) + 6 H₂O(g)

The energy generated results from oxidation-reduction chemistry.

Write the symbol for the metallic element that is oxidized in the reaction.


Write the symbol for the element that is reduced in the reaction.



What is the name of the first aluminum containing compound listed as a product of the reaction?



What is the name of the other aluminum containing compound listed as a product of the reaction?


2.

The chemical substances in the first column of the table are either already shown as cations (because they are either polyatomic ions or variably valent elements), or they are known to form cations during the making of an ionic compound. The chemical substances in the first row of the table are either already shown as anions (because they are polyatomic ions), or they are known to form anions during the making of an ionic compound. When no charge is shown, you'll have to figure out what charge an atom of the element is expected to carry as an ion. Complete the table by writing the chemical formula of the compound resulting from combining the ions at the intersecting rows and columns. Remember chemical formulas of ionic compounds do not show charges!!!

	HSO3-	P
