Is a copper penny heterogeneous?
A copper penny is heated and suspended above the surface of acetone in a beaker. The copper demonstrates heterogenous catalysis in the combustion of acetone to carbon dioxide and water. This exotherm keeps the penny glowing.Is copper penny a homogeneous mixture?
Copper is not a mixture, it is a pure element.Is copper penny homogeneous or heterogeneous or element or compound?
A copper penny is made up of many copper atoms. A copper atom cannot be broken down into any smaller, simpler particle – an atom is already the smallest particle. Since pure copper is made up of these indivisible atoms, it is classified as an element.- If they are not evenly dispersed, as is the case of coins which are different sizes and shapes and unevenly distributed, this is a heterogeneous mixture.
