1 Answer

Answer :

Chemical signals of urea: CO (NH2) 2 . Molecular mass of urea = 12 + 16 + 14 * 2 + 1 * 4 = 60 . Therefore the combination of C = ( 12/60) * 100% = 20% and the combination of O = ( 16/60) * 100% = 26.67%

(2) amount of oxygen used for biochemical oxidation Explanation: Biochemical oxygen demand or B.O.D. is the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period. The term also refers to a chemical procedure for determining this amount. This is not a precise quantitative test, although it is widely used as an indication of the organic quality of water.
