Problem
Four separate chemical processes are carried out in the laboratory under standard-state conditions. The balanced molecular equations are collected in the table below.
(1) For Reaction 1, identify the role played by each reactant (acid or base) and justify your classification by referring explicitly to proton transfer.
(2) For Reaction 2, classify the reaction type and explain how the formation of the observed product supports your classification.
(3) For Reaction 3, assign oxidation numbers to magnesium and oxygen before and after the reaction, then use those values to justify your classification of the reaction type.
(4) For Reaction 4, determine whether the process should be classified as acid–base, redox, neither, or both. Support your answer with appropriate oxidation-number or proton-transfer evidence.
