Re: 2013 Final 5 B

You put them in alphabetical order of their name. CL = Chloro while NH3=Ammine

Therefore A comes before C so you put NH3 first

Re: How to determine which is an acid and which is a base?

In this case you NH3 is a weak base due to the fact that NH3 is not completely ionized in water

Re: Covalent and Ionic Character

A short way to remember ionic and covalent bonds are:

ionic bonds: usually two atom from opposite sides, an atom from the left side with an atom from the right side of the periodic table
covalent bonds: usually two atoms on the same side of the periodic table (right side)

Re: HW question 2.17 [ENDORSED]

The question states" How many orbitals are in sub-shells will l equal to a)0 b)2 c)1 d)3" for a) you know that L=0 corresponds to a s-orbital and s orbitals have 1orbital therefore the answer is 1 orbital b) l=2 corresponds to a d-orbital and d orbitals have 5 orbitals , therefore the answ...

MOlECULAR FORMULA [ENDORSED]

When determining the molecular formula, (after figuring out the empirical formula) how do you know what number to multiply the empirical formula? For example, C3H4C3(empirical formula) with a mass spectrometry of 176.14g and the molar mass was 88.06 g mol, the empirical formula was multiple by 2 in ...
