- Fill in the following brackets: Redox reactions can also lead to greenhouse gas emissions from soils. Under very strongly reducing conditions (Eh < -0.1) the dominant GHG released from soils is likely ["carbon dioxide", or "methane", or "nitrous oxide", or "nitrous oxide and carbon dioxide"], whereas, at oxidizing conditions (Eh > +0.2) release of ["carbon dioxide", or "methane", or "nitrous oxide", or "nitrous oxide and carbon dioxide"] is more favorable.arrow_forwardPart A Silver can be electroplated at the cathode of an electrolysis cell by the half-reaction: Ag (aq) + e¯→ Ag(s) What mass of silver would plate onto the cathode if a current of 8.1 A flowed through the cell for 63 min ?
