Chapter 13 Question 25

Calculate the volume of .150 M HCl(aq) required to neutralize one half of all the hydroxide ions in 25.0 mL of .110 M NaOH(aq).

Can someone please walk me through this problem. I am confused and don't know where to begin.

Question 11.13

Write the reaction quotient Q for
(a) 2BCl3(g) + 3H2O(l) ---> NH3(g) + 3HOCl(aq)

I don't understand how the answer comes out to be 1/P(BCl3)2

Chapter 4 (Question 61)

4.61 Give the valence-shell electron configurations and bond orders for CO and CO + . Us e that information to predict which species has stronger bonds. In the answer, CO has a valence-shell electron configuration of (σ2s) 2 (σ*2s) 2 (π2p) 4 (σ2p) 22 Why would it not be (σ2s) 2 (σ*2s) 2 (π2p) 4 (σ2p...

Online Modules

I find the online modules given by Professor Lavelle extremely useful and a great resource to review material, especially for the first quiz next week. Is there a possibility of having future material (i.e chapter 2) given as modules and used as a resource?
