10 sty 2021 · To identify the strongest base we can determine their weakest conjugate acid. The conjugate acids of CH − 3, NH − 2, and S − 2 are CH4, NH3, and HS −, respectively. Next, we consider that acidity increases with positive charge on the molecule, thus ruling out that S − 2 is the weakest base.

3 cze 2022 · Well, play this acid and bases science game with kids to help them learn about acids, bases and chemical reactions. This fun game for kids will help them review key facts about chemical reactions.
What are the Lewis Acids and Bases? When delving deeper into Lewis acids and bases, it’s essential to understand their fundamental characteristics. A Lewis acid acts as an electron acceptor. Typically, any molecule or ion with an empty orbital ready to accept electrons is a Lewis acid. Some examples include: H+: A proton devoid of electrons.
