Answer 1

I can't give you anything interesting using all those ingredients, but I'll try to help.

Experiment... "what is the true cost of a penny"
Locate the market price for copper and the market price for zinc, today.

Weigh a penny.

Then take your penny (after 1984) and file off 2 sections of the edge, just file down a little bit or make 2 small cuts. You may even be able to see the zinc kind of shine through.

Place your penny in a beaker (glass) of HCL listed above. If you filed off enough copper, you will see bubbles (of Hydrogen) coming out of the file/cut areas.

Wait one day.

Return to your penny, gently remove and wash. You will notice that your penny has lost some weight! It should be fragile and paper thin. Weigh your penny. Calculate the mass of copper and the mass of zinc. Use the market prices above to determine what the cost of a copper zinc penny really is.

Find a penny from before 1984, weigh it, calculate the cost to make a pure copper penny.

Have fun!

Answer 2

Usually the "rare" experiments are that way for a reason. They are either hard to set up or not so safe to do, especially out of a lab setting.
