What is the concentration of the Mg2 ion in solution when [CO3-2] = 0.25M given that the Ksp= 6.82 x 10-6 for the following reaction MgCO3-------->Mg +. CO32- Chemistry - DrBob222, Friday, November 11, 2011 at 5:34pm Ksp = (Mg^2+)(CO3^2-) Substitute 0.25M for CO3^2- and sol...

Name 3 buffers that exist in the human body? Include the conjugate and acid base pairs

Chemistry
For the reaction 2 N2O <===>O2 + 2 N2 what happens to the equilibrium position if the pressure is increased

Chemistry
Second thought I just don't understand what to do. pH= pKa + log [NH3]/[NH4NO3] pH= -l log ? + log (0.005/?) pH= ? pH= ?

Chemistry
Don't think I know how to calculate the M of NH4NO3

Chemistry
So is it a problem if the conch of NH4NO3 was not given to me. Or do I just assume it's the same as the NH3

Chemistry
Calculate the pH buffer made by combing 50.0 mL of 1.00M ammonia and 50.0mL of ammonium nitrate. Can I use the same formula? If so do I do anything with the mL

DrBob I want to thank you SOOOOO much for all the help you give. I had never heard of the H H equation. And I also appreciate you patience

chemistry
This what I did log(1.76 x 10-5) +log(0.150/0.200) = 4.879

chemistry
No I'm sorry I just used this as the example of the H H equation
