Answer:
The BOD5 for this sample is 5 mg/L
Explanation:
The BOD5 takes into consideration the difference between the initial DO and the final DO divided by the fraction of the sample tested in a 300 mL BOD flask. The problem states that the sample was directly placed in a BOD bottle so we assume that the volume used was 300 mL of the water sample. The fraction of water is 1 (300/300).
BOD5 = (10-5)/1
BOD 5 = 5 mg/L
Along with the fact that the infrastructural and industrial levels of the African colonies was never really developed by Europeans, the many various and opposing ethnic groups had no one to keep them in check now. As a result many civil wars took place between different religions, specific religious denominations, and specific ethnic groups of said religious denominations. Also nearly all of the leaders that broke free of European rule were woefully unprepared to lead a country both governmentally and economically. All of these factors are what lead to Africa's current problems.
