well, you never know when solution stoichiometry will turn up but for thermochem, you will need mostly algebra skills and general stoichiometry. Electronic structure is conceptual and also covers trends in the periodic table.
Most programs that require a gen chem course do so for a reason. Unless you are taking it as an elective for a science requirement, your major usually has some science component that chemistry would be related to.
Aqueous reactions have everything to do with dissolving things in water and making solutions. If you've ever put salt in water, or made Koolaid or drank sports drinks or sodas or lived in a hard water area (lots of ions in the water) or took an antacid because of excess stomach acid and many more . this is all aqueous chemistry that we might encounter everyday.
