Answer:
(i) 5-day BOD of the waste is 120 mg/l.
(ii) The ultimate carbonaceous BOD (Lo) is 20 mg/l.
Explanation:
The dilution factor D is 0.05.
The initial DO is 8.0 mg/L and the DO after 5 days is 2.0 mg/L.
The BOD of the waste for an unseeded mixture is
The ultimate carbonaceous BOD (Lo) can be calculated as
The chemical name begins with Hydro The Chemical name ends with hydroxide and the ide ending is changed to ic also the polyatomic ate ending changed to ic
the produce would be water and some form of salt
hope this helps
Answer:
We add A Hydrogen
Explanation:
When we have a half-reaction in an acidic media usually we add (H+) hydrogen plus or protons to the reaction to balance in both sides of the reaction the amount of hydrogen.
After this step the next one is equilibrate the charges (e-) and finally we add the two half-reactions to write a short version
Answer:
For an element, the molar mass is the mass of 1 mol of atoms of that element; for a covalent molecular compound, it is the mass of 1 mol of molecules of that compound; for an ionic compound, it is the mass of 1 mol of formula units.
