Blue-green
The color of the precipitate formed when copper oxide (CuO) reacts with hydrochloric acid (HCl) is typically black or brown. This reaction produces copper chloride (CuCl2) along with water (H2O).
To find the number of moles, first calculate the molar mass of CuO by adding the atomic masses of copper (Cu) and oxygen (O) together. Then, divide the given mass of CuO (3.2g) by the molar mass to get the number of moles.
Cu2O is copper(I) oxide, where copper is in the +1 oxidation state, while CuO is copper(II) oxide, where copper is in the +2 oxidation state. This leads to differences in their properties, such as color and reactivity. Copper(I) oxide is red in color and is a reducing agent, while copper(II) oxide is black in color and is an oxidizing agent.
CuO is made up of Cu2+ and O2- ions. So there are two ions, per molecule of CuO.
The balanced chemical equation for the reaction between CuO and HCl is: CuO + 2HCl --> CuCl2 + H2O This equation shows that 1 mole of CuO reacts with 2 moles of HCl. Therefore, to react with 4 moles of HCl, you would need 2 moles of CuO.
Cuoh is copper(II) hydroxide and is pale blue in color. Some of these are more green than they are blue.

Copper (II) oxide is the name for CuO.
12.5 (g CuCO3) = [12.5 (g CuCO3) / 123.555 (g/mol CuCO3)] = 0.1012 (mol CuCO3)0.1012 (mol CuCO3)* [1 (mol CuO) / (mol CuCO3)] = 0.1012 (mol CuO)= [0.1012 (mol CuO) * 79.545 (g/mol CuO)] = 8.047 g CuO = 8.05 g CuO
CuO is a compound. It is not a mixture.
