One way in which acid strength is determined is by how stable its anion can be. If it is one with a greater electronegativity, you will know it is more stable because it can well distribute the negative charges throughout. The same effect applies to one with greater numbers of electronegative elemen...
You should look to molecular orbital diagrams to help determine bond stregnth. If you draw out their MO diagrams, you will see that C2- has an extra electron in the bonding molecular orbital (sigma 2pz). The more electrons you have in a bonding orbital, the stronger your bond. Conversely, the more e...

You would know to use an MO diagram for anything that is diatomic (homonuclear or heteronuclear), like Br2 in your example. If it were just Br, you would use just its atomic orbital diagram.

The hydronium concentration is still taken into account to determine pH while there is still acid in the solution- for instance before the addition of any base or after the addition of 10.0ml 0.10M NaOH. Here, only some of the acid is being neutralized and thus there are still hydronium ions generat...
Acids and bases that are relatively weak will mostly remain in its molecular form, so you wouldn't split it up when writing the start of your reaction. Conversely, all strong acids and bases will be split up because they completely dissociate in a solution.

If it is an ion, you can usually tell it has a negative charge if "-ate" is added to the end of the metal. You can also determine charge by assigning charges to each element in your complex, given ligands with their prefixes (if any) and the transition metal with its oxidation number, and ...
