Re: Acids and Bases

Is there any easy way to identify a strong acid or strong base besides just memorizing them?

Re: Calculating pH and the pOH

You could find the pH of the hydronium and then subtract that value from 14. This is because the pH and the pOH should add up to 14.

Re: Naming

I think it depends where its located. If it is supposed to be written based on the bond as OH2 then you write it as that and vice versa.

Re: Test 3

Re: Bond length

I do not think we actually have to calculate bone lengths. It is similar to the bond angle concept of just knowing that it is slightly less than 109.5 degrees.

Re: Molecular Shape

I think that shape matters more because the electron geometry is just a way for us to see it on paper, but the shape is the actually position in space. Im not sure about the hybridization part.

Re: 3d and 4s

also with ions make sure to write out the ground state configuration first so that you know to remove 4s electrons before 3d.

Re: Spin Magnetic Quantum

You can determine the spin based on how you fill the orbital. If the electron is pointing up then it has a +1/2 spin and if it is pointing down it has a -1/2 spin.

Re: Energy levels of orbitals?

I am pretty sure that the energy levels are s<p<d<f. I think this is because there are less n levels and so there are less electrons and energy at lower orbitals.

Normally you have to convert to the standard unit of measurement. Like grams and liters etc.
