Reactions occur for the following reasons.
1. An insoluble substance (precipitate) is formed. For this you need to learn the solubility tables.
2. A gas is formed. For this you need to know the gases in the periodic table plus common gases in daily use.
3. A slightly ionized substance is formed (for example H2O).
4. A redox equation occurs. These, at least in elementary courses, can be predicted from the activity series.
a. #4
b. #1
c. #4
d. #3. Acids + bases produce salt + H2O
I need help predicting the products and naming them using classes and subclasses.
a. Br2+BaI2
b. CdBr2+Na2S
c. H2+Br2
d. H3PO4+Ca(OH)2
(Numbers above are supposed to be in subscript form)
