Solution: Polishing Silver Silver tamish is the result of silver metal reacting with sulfur compounds, such as H2S, in the air. The tamish on silverware (Ag2S) can be removed by soaking in a solution of NaHCO3

Problem

Polishing Silver Silver tamish is the result of silver metal reacting with sulfur compounds, such as H2S, in the air. The tamish on silverware (Ag2S) can be removed by soaking in a solution of NaHCO3 (baking soda) in a basin lined with aluminum foil. 

Write a balanced equation for the tarnishing of Ag to Ag2S. Do not include phases. 

How many moles of electrons are transferred per mole of silver? 

Write a balanced reaction for the reaction of Ag2S with Al metal and H2O to produce Al(OH)3, H2S, and Ag metal. Do not include phases.
