i was given two compounds and told to balance
the two compounds are:
Na₂SO₄    and    NH₄Cl

i dont know where to start...

[Borek]

Balance what?

[mandy9008]

exactly...
ive attached the sheet that i was given.

Well, the handout you posted gives very good advice, as good as any I'd give you:

Solutions (Exp 26)

1.) Write in your lab notebook the balanced chemical equation for all 36 reactions. 
2.) Determine what reaction, if any, will occur when two solutions are mixed together by using solubility rules, etc. (formation of precipitate, formation of a gas, odor, etc.)
3.) Using pertinent references (CRC, Merck) look up precipitates to determine color of precipitate, etc.
4.) In many cases, there will be no reaction when two solutions are mixed together (all aqueous products); in these cases write NR for no reaction.

I boldfaced the most interesting and useful suggestions.  Also, the assignment ponts you to two primary references for you to find the preciptate color.  Apparantly, "some guy on the internet says ..." is not the sort of reference they're looking for.

yeah but i have to look up the whole chemical equation in the CRC to find the precipitates. i know how to do that. i just need to know to get an equation.

one of the answers for the reaction of KIO₃ and NaBr  is :
KIO₃ + NaBr  KBr(aq) + NaIO₃
after i get the initial reaction, i can look in the CRC to see if precipitates form and if so what color.

Is NaIO₃ also (aq)?  If so, what will cause the reaction to procede?  What will you be able to see?
