Re: Placement of Hydrogen on the Compound

When there is a hydrogen at the end and the compound is mixed with water it'll mostly act as an acid since it would give away its proton to form h3o+. You mostly have to familiarize yourself with the most common acids and bases. What I usually do though is think of it when its mixed with water and t...

Bohr Model

Use the Bohr model to calculate the radius and the energy of the B 4+ ion in the n=3 state. How much energy would be required to remove the electrons from 1 mol of B 4+ in this state?
