Document Summary
Attraction for an electron (force in volts) Iron = lose electrons and is oxidized, reducer. Oxidizer (oxidizing agent) = takes electrons (e. g. oxygen) Reducer (reducing agent) = loses/gives up electrons (e. g. iron) Uorine: in creating metal, they would reduce the rock (the oxygen) back to a metal = hence the name reduce . Battery is essentially a galvanic cell or multiple galvanic cells. Give a change value to all atoms, even those which are covalent. Ions get their charge na+ = + 1. Hydrogen is +1 e. g. what is the charge on co2. Carbon has an oxidation number of +4 e. g. clo- Cells - voltage is based on chemical reaction. Amperage is based on amt of chemical reacting. Total available energy based on total amt of chemicals present. Aa & d - same voltage; diff amount of stored energy. Primary can be recharged theoretically but not practically. Lead + h2so4 -cheap, undergo many cycles (b/c cheap, can make them large)
