Ethanol is accidentally spilled into a 500,000 m² pond, where it is degraded by microbial action according to the reaction: C2H5OH + 02 → CO2 + H2O a. Balance the reaction for microbial degradation of ethanol. b. How many kilograms of oxygen are consumed in the process if 500 lb ethanol were spilled? c. How many kilograms of CO2 are produced? d. Assume that produced CO, remains dissolved and does not partition into the atmosphere. What is the dissolved concentration of CO2? e. Assume that the dissolved CO2 concentration found in part (d) is allowed to equilibrate with an atmosphere that is initially free of CO, gas. What will be the pressure of CO2 in this atmosphere after equilibration with dissolved CO2?

Ethanol is accidentally spilled into a 500,000 m³ pond, where it is degraded by microbial action according to the reaction: C2H50H + 02 → CO, + H2O a. Balance the reaction for microbial degradation of ethanol. b. How many kilograms of oxygen are consumed in the process if 500 lb ethanol were spilled? c. How many kilograms of CO2 are produced? d. Assume that produced CO2 remains dissolved and does not partition into the atmosphere. What is the dissolved concentration of CO2? e. Assume that the dissolved CO2 concentration found in part (d) is allowed to equilibrate with an atmosphere that is initially free of CO2 gas. What will be the pressure of CO, in this atmosphere after equilibration with dissolved CO2?
