The students will need access to matches or lighters to light their Bunsen burners. Screen capture done with Camtasia Studio 4.0. Copper reacting with silver nitrate will produce copper (II) nitrate and silver. The outside of the envelope will react with oxygen in the air and will turn black. However, we can still assign oxidation states to the elements involved by treating them as if they were ionic (that is, as if all the bonding electrons were transferred to the more attractive element).
