282. Using the potentials (Tables P.6, P.7, P.8), complete the reaction equations (two for each option), making electron-ionic schemes for them. For reactions of metals with H2SO4 (conc.) and HNO3, the value of the oxidizing agent potential is more than 1 V. Estimate the practical stability of metals in this environment.
a) Al H2O O2
b) Mg HNO3 (razb.)
