alyssia_o6 asked:

NH3, H2SO4, CH3OH, CH3COOH

Please help me to understand why you are ranking them the way that you do. There are so many rules and exceptions it seems for acids and bases that it is hard for me to rank a group of more than two.

Grace J asked:

Rank the following atoms and ions
Li+, Be2+, He, H−, B3+
in order of decreasing size.

1. H−, He, Li+, Be2+, B3+
2. B3+, Be2+, Li+, He, H−
3. H−, Li+, He, Be2+, B3+
4. B3+, Be2+, He, Li+, H−
5. He, H−, Li+, Be2+, B3+

I don’t understand how you know because the number of electrons are the same.
