caffeine
Cocoa has sugar & Caffeine just like coffee & that will make it hard for you to fall asleep.
drink coffee/soda, walk around, listen to music, talk to someone
Been there, done that. Coffee and tea works best for me! Good luck! :-)
Fresh air and exercise usually helps. I was told to eat an apple, and have tried eating an apple vs a cup of coffee. The apple did help keep me awake.
Very, very unlikely. The odds are highly unlikely, and are just about as good as falling asleep an hour after drinking 5 cups of high-caffeinated coffee.
Coffee is a mixture and does not have chemical name.

coffee
Coffee is a heterogenous mixture of different compounds. It is not a single compound and does not have a chemical formula.
chemical change
I think making coffee is a chemical change because the signs for a chemical change are: there is a gas given off, a colour change,a different smell,heat given out or absorbed and the change cannot be easily reversed. In this case colour change and and a different smell are underlined and also you cannot regain the same ingredients you started with to make the coffee.
physical. the water being added simply soaks through the coffee, so there's no chemical change.
