School Science Question re Copper Oxides on Pennies

School Science Question re Copper Oxides on Pennies on copper oxide and we're using vinegar and salt for an experiment to get the tarnish off the pennies But I'm getting confused about copper (l) and copper (ll) oxide Does copper (ll) oxide produce worse tarnish on copper like making it more dull than copper (l) would or resulting in

How Do Acids Reacts With Metal Oxides?

The reaction between a metal oxide and an acid produces a salt and water The resulting mixture is warm The kind of salt produced is dependent on the specific acid used Some examples of reactions between acids and metal oxides are copper oxide with hydrochloric acid and the combination of copper oxide with nitric acid

US5482174A

Why Does Copper Oxidize and Turn Green?

Feb 20 2018The copper metal reacts with oxygen resulting in the formation of an outer layer of copper oxide which appears green or bluish-green in color This layer is known as the patina Unlike other destructive oxidation processes the patina acts as a protective layer and it does not cause any weakness in the metal

Copper

The resulting copper matte consisting of Cu 2 S is roasted to convert all sulfides into oxides 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2 The cuprous oxide is converted to blister copper upon heating 2 Cu 2 O → 4 Cu + O 2 The Sudbury matte process converted only half the sulfide to oxide and then used this oxide to remove the rest of the

Neutralizing Viruses in Suspensions by Copper Oxide

Apr 30 2007We report the capacity of copper oxide-containing filters to reduce infectious titers of a panel of viruses spiked into culture media Enveloped nonenveloped RNA and DNA viruses were affected suggesting the possibility of using copper oxide-containing devices to deactivate a wide spectrum of infectious viruses found in filterable suspensions

Copper

Finally the resulting crude copper is purified by electrolysis involving plating onto pure copper cathodes Isotopes Copper has 24 isotopes whose half-lives are known with mass numbers 57 to 80 Naturally occurring copper is a mixture of its two stable isotopes 63 Cu and 65 Cu with natural abundances of 69 2% and 30 8% respectively
