46. Solving a chemistry problem

Using the potentials (see the table "Redox potentials of hydrogen, oxygen and some metals in different media"), complete the reaction equations (two for each option) and draw up electron-ion schemes for them. For reactions of metals with concentrated H2SO4 and HNO3, take the value of the oxidizing agent potential to be more than 1 V. Estimate the practical stability of metals in this medium.
