Answer true or false. (a) When a substance is oxidized, it loses electrons. (b) When a substance gains electrons, it is reduced. (c) In a redox reaction, the oxidizing agent becomes reduced. (d) In a redox reaction, the reducing reagent be comes oxidized. (e) When Zn is converted to Zn2 ion, zinc is oxidized. (f) Oxidation can also be defined as the loss of oxygen atoms and/or the gain of hydrogen atoms. (g) Reduction can also be defmed as the gain of oxygen atoms and/or the loss of hydrogen atoms. (h) When oxygen, O2, is converted to hydrogen per oxide, H2O2, we say that O2 is reduced. (i) Hydrogen peroxide, H2O2, is an oxidizing agent. (j) All combustion reactions are redox reactions. (k) The products of complete combustion (oxidation) of hydrocarbon fuels are carbon dioxide, water, and heat. (l) In the combustion of hydrocarbon fuels, oxygen is the oxidizing agent and the hydrocarbon fuel is the reducing agent. (m) Incomplete combustion of hydrocarbon fuels can produce significant amounts of carbon monoxide. (n) Most common bleaches are oxidizing agents.
