2. An effluent waste stream contains 3300mg/L organic matter ((CH2O) suspended and dissolved) and 27mg / L ammonium ion NH4+ (as N). Write chemical equations for the complete oxidation of (CH2O) and NH4+ and calculate the total BOD of this effluent in mg/L O2

I had 1.0 mL of 1.0M CoCl2 in a test tube.  I put it into boiling water.  [Co(H2O)6]2+, [CoCl4]2-  Equilibrium temperature effect.  Effect of heat What happens to the equilibrium?  Use this equation in your explanation... 4Cl_ (aq) + [Co(H20)6]2+(aq)---[CoCl4]2-(aq)+ 6 H20 (l) I did this in class.  The color change was very slow but it changed from a burgandy to fushia.

3.02 g of sodium sulfate was mixed into a solution containing 48.5 mL of 0.185 mol/L aqueous silver nitrate:   Calculate the maximum mass (in g) of precipitate that can form.   Note: Balanced chemical eq. with state of each compound required.       2. What is the molar concentration of sodium ions in the resulting solution?
