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
CU+2 H3C-COOH=CU (H3C-COO)2+H2
CU=copper
2 H3C-COOH=vinegar
CU (H3C-COO)=Hexaaquacopper (the blue liquid left afterwards)
H2= Helium
H=hydrogen not helium..... dont trust this answer.
Copper + Oxygen -> Copper Oxide
Cu + O2 (its diatonic) -> CuO
and if u want that balanced its :
2Cu + O2 -> 2CuO
There is no "chemical equation" but, the chemical makeup is 95% Copper (Cu) and 5% Zinc (Zn). This is for pre-1982 pennies only. After 1982 pennies are mostly Zinc.
It is not a chemical change.
copper
Yes. Dissolution of a copper penny would indeed be a chemical reaction.
The chemical equation is:Zn + CuSO4 = ZnSO4 + Cu
Chemical.
HCL and copper oxide = Copper chloride+water

Yes. Dissolution of a copper penny would indeed be a chemical reaction.
The chemical formula (not equation) is CuSO4.5H2O.
The chemical formula (not equation) of copper(II) sulfate is CuSO4.
The chemical equation is C7H4O9
The chemical equation is:Zn + CuSO4 = ZnSO4 + Cu
The chemical formula (not equation) of copper(II) chloride is CuCl2.
Chemical.
HCL and copper oxide = Copper chloride+water
CuCl

The chemical formula for copper oxide is CuO.
The chemical formula (not balanced symbol equation) of copper (II) cabonate is CuCO3.
