Calculate the degree of ionization of acetic acid in solution 1 through 3? All I am giving is the pH... pH of solution 1= 3 pH of solution 2= 3.5 pH of solution 3= 5 Then, I did this... HC2H3O2 (aq) + H2O (l) equals H3O+ (aq) + C2H3O2- (aq) Ka= 1.7 E -5 (according to chart in ...

If some NH4Cl is added to an aqeous solution of NH3: A. pH of solution will decrease B. PH will not change C. pH will increase D. NH4Cl cannot be added to NH3 E. The solution will not have pH I think the answer is B, because if NH4Cl is added to the solution of NH3, then solut...

Thanks. Is there a way to tell how one acid is weaker than the other or do you have to memorize the charts?

Determine the direction of the following reaction from the relative strengths of acids and bases: H2S(aq) + C2H3O2-(aq) yields Hc2H3O2(aq) + HS-(aq) The book says this will favor the reactants. I'm confused...shouldn't this be neutral because both reactants and product...

At 900.0K, the equilibrium comstant (kp) for the following reaction is 0.345 2SO2 (g) + O2 (g) yields 2SO3 (g) At equilibrium the partial pressure of SO2 is 35.0 atm and that of O2 is 15.9 atm. What is the partial pressure of SO3 in atm? 6.20 X 10-4 ( I think it is this one) 1...

I think I tried to do the ICE and got... 2.06/2.00=1.03 M 0.0227/2.00=0.0114 M but got lost after that and ended up with 1.73 X 10-6...I am really struggling on these problems...

2NF3(g) yields N2(g) + 3F2(g) When 2.06 mol of NF3 is placed in a 2.00L container and allowed to come to equilibrium at 800K, the mixture is found to contain 0.0227 mol of N2. What is the value of Kp at this temp? 1.91 X 10-3 1.73 X 10-6 (think this is it) 4.43 X 10-7 1.83 X 10-3
