What will we observe when dilute hydrochloric acid is added to a small amount of copper oxie in a beaker?
When dilute hydrochloric acid is added to copper oxide in a beaker, a chemical reaction occurs where the acid reacts with the oxide to form copper chloride, water, and releases carbon dioxide gas. This reaction will be observed as bubbling or fizzing due to the release of the gas. The color of the solution may change as well, from blue-green to a light blue due to the formation of copper chloride.

What is copper hydroxide plus hydrochloric acid?
When copper hydroxide reacts with hydrochloric acid, it forms copper chloride and water. This reaction involves the exchange of ions between the copper hydroxide and the hydrochloric acid.
Which salt will be made when copper oxide reacts with hydrochloric acid?
When copper oxide reacts with hydrochloric acid, it forms copper chloride and water.
What is the word equation for when hydrochloric acid reacts with copper oxide?
Balanced equation: CuO + 2HCl --> CuCl2 + H2O Word equation: One mole of copper (II) oxide plus two moles of hydrochloric acid produces (or yields) one mole of copper (II) chloride plus one mole of water.
What metal is most reactive with hydrochloric acid out of magnesium and copper?
Magnesium is more reactive with hydrochloric acid compared to copper. When magnesium reacts with hydrochloric acid, it produces hydrogen gas and magnesium chloride, while copper does not readily react with hydrochloric acid.
When an oxidised copper coin is placed in a beaker of hydrochloric acid why does it turn shiny?
When a copper coin is oxidized, it forms a dull layer of copper oxide on the surface. When placed in hydrochloric acid, the acid reacts with the copper oxide layer to form copper chloride, which is soluble in the acid. This process removes the oxide layer, revealing the shiny copper surface underneath.
What is copper hydroxide plus hydrochloric acid?
When copper hydroxide reacts with hydrochloric acid, it forms copper chloride and water. This reaction involves the exchange of ions between the copper hydroxide and the hydrochloric acid.
Which salt is produced when copper oxide reacts with hydrochloric acid?
Copper oxide and hydrochloric acid will produce copper chloride.

Why doesn't copper react with hydrochloric acid?
Copper does not react with hydrochloric acid because it is a less reactive metal and does not displace hydrogen from the acid.
Does copper oxide react with hydrochloric acid?
Yes copper oxide reacts with hydrochloric acid and it forms a blue green compound.
What is the chemical reaction between copper and hydrochloric acid (Cu HCl)?
When copper reacts with hydrochloric acid (Cu HCl), it forms copper chloride (CuCl2) and hydrogen gas (H2).
Write a word equation for copper oxide?
The chemical formula for copper oxide is CuO.
Chemical equations of hydrochloric acid and copper oxide?
The product is copper ii chloride alongwith water, CuO + 2HCl = CuCl2 + H2O
What would happen if you diluted magnesium and copper with hydrochloric acid?
When magnesium is diluted with hydrochloric acid, it will react to form magnesium chloride and hydrogen gas. The reaction with copper and hydrochloric acid will not occur unless the copper is in a powdered form, as the acid cannot penetrate the protective oxide layer on the surface of solid copper. If powdered copper is used, it will react with hydrochloric acid to form copper chloride and hydrogen gas.
