1st and 3rd reaction:

Dissolving those compunds in water you get a mixture of anions and cations: the only reaction possible is the precipitation of an "insoluble" salt. Checking the Ksp values you'll see that:

(CaSO4) Ksp=2.4∙10-5
(BaSO4) Ksp=1.1∙10-10

2nd reaction:

It's simply the oxidation of an alkali metal due to oxygen. What is the only oxidation state of alkali metals?

There is no simple answer to second reaction, as it depends on the conditions. The most obvious answer is the wrong one.
