What equation is sulphuric acid mixed with copper oxide?
Cu + 2H2SO4 -> CuSO4 + 2H2O + SO2 Copper (Cu) on reacting with two moles of sulphuric acid (H2SO4) yields copper sulphate (CuSO4) and 2 moles of water (2H2O) and sulphur dioxide (SO2).
What happens if you mix copper oxide and sulphuric acid?
When copper oxide is mixed with sulfuric acid, a chemical reaction occurs that forms copper sulfate and water. The copper oxide reacts with the sulfuric acid to produce copper sulfate while the water is a byproduct of the reaction. This is a common method for preparing copper sulfate in a laboratory setting.
Copper sulphate can be made by mixing what acid?
When copper (ii) oxide is mixed with sulphuric acid it produces copper (ii) sulphate. CuO + H2SO4 = CuSO4 + H2O
What do hydrogen sulphide and copper sulphate form when mixed together?
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.
What residue is left behind when copper carbonate is hot or cold?
When copper carbonate is heated, it decomposes to form copper oxide and carbon dioxide gas, leaving behind copper oxide residue. When copper carbonate is mixed with acids to produce copper salts, a blue residue may be left behind.
What is mixed with copper oxide to make copper sulphate?
Sulphuric acid is mixed with copper oxide to make copper sulphate through a chemical reaction.

What was zinc used for in the ancient times?
mostly mixed with copper and heated to make brass
What happens if acid is mixed with copper?
it depends what acid it is
Copper sulphate can be made by mixing what acid?
When copper (ii) oxide is mixed with sulphuric acid it produces copper (ii) sulphate. CuO + H2SO4 = CuSO4 + H2O
What happens when sulphuric acid is mixed with sodium carbonate?
Sodium Sulphate, Carbon Dioxide and Water OR Carbonic Acid
What do hydrogen sulphide and copper sulphate form when mixed together?
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.
What happens to copper when mixed with limewater?
When copper is mixed with limewater, no immediate reaction occurs. Limewater is a solution of calcium hydroxide, which is not reactive with copper. However, if copper is exposed to air and moisture over time, it may develop a greenish layer of copper carbonate on its surface.
What residue is left behind when copper carbonate is hot or cold?
When copper carbonate is heated, it decomposes to form copper oxide and carbon dioxide gas, leaving behind copper oxide residue. When copper carbonate is mixed with acids to produce copper salts, a blue residue may be left behind.
What happens when tin is mixed with copper sulphate?
No product is produced. Both cooper and tin are not reactive metals.
What happens to Copper sulfate and sodium hydroxide when mixed together?
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.
