Subject: Balanced equation for the decomposition of acetone with Cu as a catalyst?

I have found a wonderful demonstration where copper acts as a catalyst 
in the decomposition of acetone. In the demo, a penny that has been 
heated in a flame, is suspended over a small amount of acetone in a 
beaker. As the vapors of acetone rise, the penny facilitates the 
reaction and continues to glow red-hot as the reaction is fairly 
exothermic. What I need is a balanced chemical equation that 
represents this process. Acetone in the presence of Cu yields ? + ?? 
It seems like this ought to be pretty simple but I have yet to find an 
answer. Thank you for your time and effort. Steve Cole (General
