Consider the titration of 100.0 ml of 0.050 M NH3 with 0.10 M HCl. Calculate the pH at the following volume of HCl added: 60.0 ml. Type in final answer! Kb for NH3 = 1.8 x 10-5  

Balance the following equations in the media noted. In base:            Cr(OH)4ˉ +  OClˉ →  CrO4ˉ2 +  Clˉ Note: final answer goes on your work paper!

Those students who complete the academic path and graduate will receive  ____________. a.  an Associate of Arts degree b.  an Associate of Applied Science degree c.  a Certificate of Completion

If a student receives an “I” for incomplete work, he/she has one year to complete any unfinished work and to prevent the grade’s becoming an “F.”
