what is the chemical formula of a penny? ________________________________________________________________________ Wow, you're a gord. Pennies are interesting things. If they're pre-1982, they're primarily composed of Copper (Cu). However, pennies since then are made of Zinc (Zn) and coated with Copper. source: http://coins.about.com/od/uscoins/f/copper_to_zinc.htm and http://answers.Yahoo.com/question/index?qid=20080509170406AAZirK2
Yes. Dissolution of a copper penny would indeed be a chemical reaction.
The balanced chemical equation for copper sulfate is: CuSO4 + H2O → CuSO4•5H2O
Chemical.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
The chemical equation for copper chloride can be represented as CuCl2, where Cu is the symbol for copper and Cl is the symbol for chlorine. Copper chloride is formed when copper reacts with chlorine gas.

The chemical formula (not equation) of copper(II) sulfate is CuSO4.
Chemical.
The chemical equation is C7H4O9

Word equation: Iron + Copper (II) sulfate → Iron (II) sulfate + Copper Chemical equation: Fe + CuSO4 → FeSO4 + Cu
HCL and copper oxide = Copper chloride+water
