Hi!
I am helping a girl with homework. I have been doing fine but then she brought out this science worksheet (but no textbook where I could read about it, because I had no idea)
If you break down each of the following, how many different substances would you recover?
Mercury
Sodium chloride
Water.....I guessed hydrogen and oxygen
Carbon dioxide
Oxygen
The questions were all about elements versus atoms and the element table.
Love,
Mom

P.S. Suzi did send me the answers!
