What is the chemical equation of a copper penny?

Answer 1

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

Answer 2

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.

Answer 3

Copper + Oxygen -> Copper Oxide

Cu + O2 (its diatonic) -> CuO

and if u want that balanced its :

2Cu + O2 -> 2CuO

Answer 4

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.

Answer 5

It is not a chemical change.
