Instructions for Part B: Use the activity series at the right to determine which reactions will occur. For those reactions that will occur, identify the oxidizing and reducing agents, and write a balanced molecular equation and net ionic equation. Magnesium ribbon is combined with aqueous copper (II) chloride. Ox agent: Red agent: Balanced molecular equation: Strength as reducing agent Li к Ba Can displace H2 from water Са Na Mg AI Mn Zn Can displace H2 from steam Cr Fe...
