Ok i need help
are alcohol and ethanol the same thing?
if i am correct
ethanol is a simpler form of alcohol
or mabe its just called ethanol when its purer, like 95/100%????

say i am right
then could you substitute a good vodka for ethanol?
or mabe something like rubbing alcohol?

if I were using vodka for my..... experiment
would it still have a carbon structure capable of bonding like pure ethanol would?

The equation for the decomposition of silver oxide is 2Ag2O---4Ag + O2. Set up a proportion to calculate the number of silver atoms produced and the number of oxygen molecules released when one g of silver oxide is broken down. There are 2.6 x 10 to the 21st power molecules in one g of silver oxide. Help me I'm so stuck................
