Why do vinegar and salt clean iron oxide from pennies?
Vinegar and salt solution, the acetic acid from the vinegar dissolves the copper oxide. The copper from the copper oxide stays in the liquid
How do you separate copper from copper oxide?
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
Copper dissolves in nitric acid producing copper nitrate After a reaction with sodium hydroxide and heating copper nitrate changed to copper oxide Calculate the percent yield?

What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
What colour is copper oxide and why?
Copper has two oxides. Copper (I) oxide is red, while Copper (II) oxide is black.

What is the compound Cu20?
Cu2O, where the 2 should be a subscript, is copper(I) oxide or cuprous oxide to give it its old name. It is found naturally as the ore cuprite. It is a red-brown powder, whereas the copper(II) oxide we see when copper is heated is black.
What is the name for the compound Cu2O?
Copper (I) Oxide or Cuprous Oxide
What is the name of Cu2O?
CuO = Cupric Oxide Cupric = Cu2+ and is not Cu The correct answer would be CuO = Copper Monoxide Copper (II) oxide is the name of the compound CuO.
Will cola clean a copper penny?
Soda pop is a mild acid, because of dissolved carbon dioxide. Acid dissolves the copper oxide tarnish that darkens the penny's color.
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
What dissolves iron oxide?
vinegar and salt dissolves it
What is created when a penny sits in a paper towel wrapped in vinegar?
Pennies get dull over time because the copper in the pennies slowly reacts with air to form copper oxide. Pure copper metal is bright and shiny, but the oxide is dull and greenish. When you place the pennies in the vinegar solution, the acetic acid from the vinegar dissolves the copper oxide, leaving behind shiny clean pennies.
What is the formula of copper (II) oxide?
The formula for copper(II) oxide is CuO. This is the commonly met black powder. Copper(I) oxide also exists. This is a red powder, and its formula is Cu2O where the 2 should be a subscript.
What colour is copper oxide and why?
Copper has two oxides. Copper (I) oxide is red, while Copper (II) oxide is black.
