Webchloroplast -Autotrophs producing energy from light and CO2 -Photosynthetic bacteria had 1 photosystem, used hydrogen sulfide (H2S) instead of water, with 2 photosystems there is enough redox power to fully oxidize water (cyanobacteria), can use water to photosynthesize ands grow much larger since water is very abundant -Calvin cycle in … WebAnswer: Nitric acid is an oxidizing agent. The nitrogen in the nitrate is reduced as sulfide is oxidized. H2S(aq) + HNO3(aq) → NO(g) + S(s) + H2O(l) 3(H2S → S ... WebIn the oxidation number change method the underlying principle is that the gain in the oxidation number (number of electrons) in one reactant must be equal to the loss in the oxidation number of the other reactant. Step 1. Write down the unbalanced equation ('skeleton equation') of the chemical reaction. All reactants and products must be known. discount rings softball
