NEED ITS SOLUTION ASAP.

A2. [35 marks] A mixed wastewater from different sources has been tested for its composition and the simplified formular is C5H6O3 at a concentration of 1000mg/L, there are two types of processes to degrade the organic compounds in this wastewater, aerobic degradation and anaerobic digestion. The two reactions are given below: C5H6O3+5O2=5CO2+3H2OC5H6O3+2H2O=2.5CH4+2.5CO2 Based on these reactions, answering the following questions. (a) To treat 1L of wastewater, how much oxygen (in gram) is required using the aerobic method? [10 marks] (b) To treat 1L of wastewater, how much methane (in L ) is produced using the anaerobic method? Assuming gas temperature is 25C and pressure is 1atm. [15 marks] (c) Which method do you recommend? Discuss the reasons to support your recommendation
