Assign oxidation state of sulfur in H2S.

If you plan to remove copper ions from acid mine drainage by precipitating them as copper oxide and copper hydroxide minerals through the addition of NaOH, to what pH will you adjust the solution to minimize copper ion concentration?  

You conducted adsorption experiment and presented your data in Cw (concentration in liquid at equilibrium) and Cs (concentration on adsorbent). Then you wanted to decide which adsorption model describe your data better. To test Langmuir model, what should be your x-axis and y-axis? See the slide note here:  

If you decide this is the best model for your reaction, what information you can learn from this experiment? Choose all that apply. 

If you are growing bacteria in a batch reactor and want to know bacteria concentration with time. What assumptions can you make for mass balance? Choose all that apply. 

Match the same reaction kinetics models.

Why can activity be assumed to be equivalent to molarity in water chemistry, while this assumption may not be valid in other fields of chemistry? (Choose all that apply)

What assumptions can you make if a reactor mixes the entire solution completely? 

What are the different types of plagiarism?

You must cite pictures, graphs, and charts when used in an academic assignment, unless you took the picture, made the graph or chart.
