### Re: Q in Practice Test 2, #5

So in order to know which way a reaction will go (ie. creating more reactants or products), you must know K, correct? You have to know K in relationship to Q. You can also tell which way a reaction will go if they give you information about concentration, pressure, volume, or temperature and if it ...

### Re: Chemical Formula

Also when you write out the name the ligands go in alphabetical order based on the name of the ligand, not it's greek prefix

### Pressure

When there are the same amount of moles on both sides of a reaction and the pressure is increased or decreased is there no shift in the way the equilibrium lies?

### Re: Quiz 3 Preparation Fall 2013 Quiz: #10

First, solve for K with the initial conditions, (7.6)(4.9)/(1.08) 2 will give you K=31.927 Next make your ICE table for the change 2BrCl <---> Br 2 + Cl 2 I .5(1.08) 4.9 7.6 C + 2x -x -x E .54 + 2x 4.9 -x 7.6-x now you solve for X 31.927= (4.9-x)(7.6-x)/(.54+2x) 2 X= .025 .54 + 2(.25) = 1 bar

### Quiz 3 Question

How do you do this?!? N 2 + 3H 2 <---> 2NH 3 deltaH = -92.22kL/mol The equilibrium mixture was found to contain 1 mol N 2 , 3 mol H 2 , and 36% by volume of ammonia at 400 degrees C and total pressure of 200 atm, Calculate the value of the equilibrium constant (K p ) and partial pressure of nitrogen...

### Coordination Compound Equations

How do you get this answer? Question: Given that the coordination number of silver is 2, please write down an ionic equation to explain how AgCl dissolves in water at the presence of excess NH3. Note: ammonia is a stronger ligand than chlorine Answer: AgCl (s) + 2NH3 (aq) --> Ag(NH3) 2 + (aq) + Cl- ...

### Re: Homework Question 69

How small does the K value have to be to allow us to create new initial concentrations? And would the answer be incorrect if we did it out without creating new initial concentrations?

### Coordination Number

How do you find out what the coordination number is without drawing out the molecule? For example with the molecule [Co(en)2]Cl3, why is the coordination number 6?
