5. Potassium bromate, KBrO3, is an additive to some flour (brominated flour) used to improve texture in the dough. It is a suspected carcinogen and some consumer groups want to ban this additive. The industry says that this compound is decomposed to KBr and O2 when the bread is baked and is thus not a risk to the health of the consumer...hmmm. When this reaction is balanced, the sum of the coefficients for the KBrO3 and KBr and O2 will be... Can you think of an easy experiment to test the response made by industry?...answer (d).
	(a)	3.5
	(b)	5
	(c)	7
	(d)	experiment

6. An iron nail was immersed in a solution of copper sulfate and when it was removed from the solution, it was coated with a layer of copper metal. After a different iron nail was immersed in a solution of zinc nitrate and removed, this nail rusted just as rapidly as a new iron nail. Rank these three metals in order of activity from most active to least active.
	(a)	Zn > Cu > Fe
	(b)	Fe > Cu > Zn
	(c)	Zn > Fe > Cu
	(d)	Cu > Fe > Zn
