Re: Practice Final 2015 #5A

I tried to calculate the formal charge and got +1 so I am also confused as to how it is negative.

Fall 2012 Final #5b

Write the formula for the following coordination compound.
triamminetrichloronickel(IV) sulfate
answer: [Ni(Cl3)(NH3)3]2 SO4

I understood how they got everything except for the 2 outside of the bracket. Can someone explain why it is 2 because I got 1? Thank you!

Re: Why is water always a monodentate?

Both of the lone pairs are on the oxygen and oxygen binds only once to the central metal so it is mono dentate.

Equilibrium Constant vs Reaction Quotient [ENDORSED]

Since you calculate the reaction quotient Q and the equilibrium constant K using the same method, how will you be able to compare the two values to determine the direction it will go? Wouldn't they be the same value?

Re: 4.61 Homework Question

Why is (sigma 2p) raised to 22 instead of 2? I made the MO diagram and got 2 for CO and 1 for CO+ in the sigma 2p.

Fall 2014 Midterm #7

The problem asks to draw the lowest energy Lewis structure of HClO3. I drew the Lewis structure as a tetrahedral shape and got zero formal charges for all of them, but when I checked with the answers, it was a trigonal pyramidal structure. Can someone explain what I did wrong and the easiest way to ...

Building Up Principle [ENDORSED]

In the course reader, there was an example pertaining to the Building Up Principle. It was given that Z=6 and (1s^2)(2s^2)(2px^1)(2py^1). In the periodic table, it says (2s^2)(2p^2). I don't understand how the 2p^2 got split into (2px^1)(2py^1). Can someone explain it? Thanks.

Re: Uncertainty

Don't you have to double the speed since it is +/- ? Instead of doing the division with 0.55, I used 1.1 and got 3.2 * 10^-32 as the answer.

Quiz 1 Prep Fall 2014 #9 [ENDORSED]

Calculate the de Broglie wavelength of a 0.155 kg ball travelling at 85.0 m.s^-1. The answer I got was 5.03 * 10^-35 m. On the answers page, they said it was 5 * 10^-35 m. I do not understand how they ended up with one significant figure. I thought there were three so I rounded to three. Can someone...

Bohr Frequency Condition

Can someone explain the Bohr frequency condition? I do not understand its application or where the upper and lower energy values come from for the formula.
