When to use Equilibrium arrow vs. reaction arrow [ENDORSED]

I noticed that in the textbook, they used a reaction arrow (---->) when there was a weak acid involved. I thought that weak acids and bases aren't completely disassociated in water. Wouldn't you need to use the equilibrium arrows in this case?

Test 4 Topic: Le Chatelier's Principle

On the course website it says that Test 4 will cover up to the end of 11.8 in the textbook, and Le Chatelier's principle is the last topic for 11.8. Will that principle be on our test even though we haven't covered it in class?

Unequal Reactant

What happens when you have more reactants than products? Does the equilibria sign lean to the left.

Ionization energy vs. Atomic radii

Why is it that some people determine the central atom based off the atomic radii and not the ionization energy? Aren't there exceptions for carbon and oxygen for the ionization energy?

HW Problem 4.15c

The structure is COF2 and the name is trigonal planar. Why is it that the Oxygen gets the double bond, but one of the Fluorine's does't get it? I thought that the most electronegative element will get the double bond? And oxygen is less electronegative than fluorine.

Re: Hybrid orbitals

The formula basically explains that new hybrid orbitals are made of old atomic oribtials like s px, py, pz, etc. For example the sp^2 hybrid orbitals are made of one s orbital and two p orbitals (px and py orbitals) Does this refer to the formation of sigma and pi bonds? Because I know that the pi ...

3d, 4s orbital

Why is it that the 3d orbital comes before the 4s? I was speaking with a physicist earlier today and he said that there's two ways people usually write it: 3d,4s or 4s,3d.
