The heat of fusion of sodium metal is 630 cal/mol. How much heat (in kilocalories) is required to melt 179 grams of sodium
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..
