- 36. Balance these ionic redox equations using the ion- electron method. These reactions occur in basic solution.Write “true” or “false” for each statement. (a) We balancechemical equations as we do because energy must be conserved.(b) If the reaction 2 O3(g)S 3 O2(g) goes to completionand all O3 is converted to O2, then the mass of O3 atthe beginning of the reaction must be the same as the massof O2 at the end of the reaction. (c) You can balance the“water-splitting” reaction H2O(l)S H2(g) + O2(g) by writingit this way: H2O2(l)S H2(g) + O2(g).The psychoactive drug methamphetamine ("speed"), which is sold as the prescription medication Desoxyn, C10H15N, under- goes a series of reactions in the body; the net result of these reac- tions is the oxidation of solid methamphetamine by oxygen gas to produce carbon dioxide gas, liquid water, and an aqueous solution of urea, CH4N₂O.
