Describe, step by step, how you would separate the cations (Ag+, Ba2+, Zn2+) from the following mixture by precipitating each ion out of the solution: AgNO3(aq), Ba(NO3)2(aq), Zn(NO3)2(aq).
You can choose the solutions you would use (ie. HCl, H2SO4).
Remember to identify the state of each compound as either solid (s) or aqueous (aq).
Suppose a piece of silver jewelry contains 6.18×1022 atoms of silver (Ag). How many dozens of silver atoms are in the piece of jewelry?
The initial DO of the mix is 9.0 mg/L. After 5 days, the DO is 4.0 mg/L. After a long period of time, the DO is 2.0 mg/L, and it no longer seems to be dropping. Assume nitrification has been inhibited so the only BOD being measured is carbonaceous..
