Question 1. If you have a gas furnace it is important to make sure that it is tuned up with a proper flow of oxygen. Without a proper flow of oxygen to the furnace, it can burn the natural gas (CH4.) with some incomplete combustion. Why can it be so dangerous if your furnace is burning natural gas with incomplete combustion?

Question 2. Complete the dissociation reactions for the following ionic compounds when

they dissolve in water:

a) Nal(s) →

b) Ba(OH)2(s) →

c) (NH4)3PO4(s) →

Question 3. Write the balanced chemical reaction, the total ionic equation, the spectator ions, and the net ionic equation for each of the following sets of reactants:

a) Aluminum nitrate + potassium hydroxide

b) Tin (II) chloride + sodium phosphate

c) Lithium + copper (II) chlorate

d) Hydrochloric acid (HCl(aq)) + aluminum
