How many moles of aluminum metal can be deposited when .6 moles of electrons are passed through 4 moles of molten Al2O3?
An insulated one is least likely to burn what's on itParchment paper provides no insulation at all and will not prevent anything from burning; it's only used to stop things from sticking to the baking sheet.
Dark sheets are supposed to cause more browning on the bottomsI use both dark and light colored heavy aluminum baking sheets on all the oven rack positionsIn a regular oven it's necessary to turn the trays halfway in the baking timeIf you have a convection oven, turning shouldn't be necessary but when using 3 racks at a time, I've noticed some uneven baking and it's probably because some of the air flow is blocked or diverted by the edges of the baking sheets.

I disagree with the stainless, I don't like the dark cookie sheets, including black steel as they seem to over brown and over crisp a cookie too quicklyYou need to go with the aluminum one, invest in a couple of half sheet cookie sheets, i got mine at Sam's clubI bought mine about 6 years ago and I will never use anything else, I clean them lightly with an sos pad and they still look brand new, I don't even have to scrub much, they still cost around 11.00 for a set of two, I paid 10.00You won't need parchment paper, just a light spray, parchment paper or my trusty sil pats, silicone linersAluminum is a great conductor of even heat, no hot spots or burning.
Since there is much more than 0.2 mole of Al in 4 moles of Al2O3, the Al2O3 is in excess and the electrons are the limiting reactant.]
