please help

2-2 Chemoautotrophic bacteria are responsible for the oxidation of NH:-N to NO -N in many biological wastewater treatment processes. These bacteria, collectively called nitrifiers, consist of the genera Nitrosomonar and Ntro- bacter. The oxidation of ammonia to nitrate is considered a two-step sequen- tial reaction as follows: overall reaction NIHI 2oNO- 2r -H,O Considering the overall reaction, use stoichiornetric calculations to show how many mg t of alkalinity as CaCos are destroyed and how many mgć of oa are required for the oxidation of 1 mg/l of NH4-N to NO,-N. 2-3 In denitrification Kan anaerobic respiration process), nitrates and nitrites resulling in the production of a smaller quantity of waste sludge. Explain this characteristic on the basis of energy metabolism. 2-2 Chemoautotrophic bacteria are responsible for the oxidation of NH:-N to NOİ.N in many biological wastewater treatment processes.

NOi + 2H+ + H2O onsidering the overall reaction, use stoichiometric calculations to show how many mgiC of alkalinity as CaCO, are destroyed and how many mglt of O2 are required for the oxidation of 1 mg/l of NHİ-N to NO-N.

Answer 1

It would require 3.55mg/L of O2.

For alkaiualy 202 2 18 V 84 20

And can can destroy 3.33mg/L of CaCO3.
