Shape of the orbitals
In a hydrogen atom the 2s and 2p orbitals have the same energy. However, in a boron atom, the 2s electrons have a lower energy than the 2p. Explain this in terms of the shape of the orbitals.

A student had 1.00 L of a 1.00 M acid solution. Much to the surprise of the student, it took 2.00 L of 1.00 M NaOH solution to react completely with the acid. Explain why it took twice as much NaOH to react with all the acid.
Assume that the activation energy for a certain reaction is 173 kJ/mol and the reaction is started with equal initial concentrations of reactants.
For the reaction A --> B, the activation energy is Ea = 125 kJ/mol and the heat of reaction, H = 50 kJ/mol. What is Ea for the reverse reaction in kJ/mol?
