You and a friend are out collecting samples in a swine lagoon and run a chemical analysis and sequence the sample. Your results come back with a chemolithoautotrophy that oxidizes sulfide - completely to sulfate - coupled to the reduction of nitrate to nitrogen gas. The concentrations of the chemicals from the chemical analysis is 300μM

You and a friend are out collecting samples in a swine lagoon and run a chemical
analysis and sequence the sample. Your results come back with a chemolithoautotrophy
that oxidizes sulfide - completely to sulfate - coupled to the reduction of nitrate to
nitrogen gas. The concentrations of the chemicals from the chemical analysis is 300μM
sulfide, 100μM sulfate, 400µM nitrate, and 50μM nitrogen gas. Find the AG based on
the scenario above (will require you find redox equation and find the AGº).
