Is forming a bar of copper into a wire chemical or physical change?
Physical. It is simply changing the shape or configuration of solid copper to another shape. Chemical changes cannot be reversed.
Is this a physical or chemical change forming a bar of gold into wire?
Forming a bar of gold into wire is a physical change. This is because the gold is being physically reshaped without undergoing a chemical reaction. The properties and composition of the gold remain the same throughout the process.
What change is expected in the reaction mixture if a copper wire is kept immersed in AN Iron sulphate solution?
The copper wire will undergo a redox reaction where it will displace iron from iron sulfate solution, forming copper sulfate and solid iron. The color of the solution will change to blue as copper sulfate forms. Over time, the copper wire will start to dissolve and the iron will start to plate out onto the wire.
What is the evidence that indicates that both physical and chemical changes occur when a copper wire is heated in a Bunsen burner flame?
When a copper wire is heated in a Bunsen burner flame, the copper's color changes to become a glowing red. It won't be restored to its original appearance after cooling. Instead, it becomes a black material called copper (II) oxide, which is 79.9% copper and 20.1% oxygen (was 100% copper before it was burned). This chemical change occurred as the oxygen in the air combined with the copper during the heating process.
Is stretching wire into copper a physical or chemical change?
Stretching wire into copper is a physical change because the composition of the material remains the same. The rearrangement of copper atoms in the wire does not alter the chemical identity of the substance.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
What happens when copper wire is dipped in ferrous sulphate solution?
When copper wire is dipped in ferrous sulfate solution, a displacement reaction occurs where copper displaces iron from ferrous sulfate, forming copper sulfate and iron. As a result, the copper wire will become coated with a reddish-brown deposit of iron.
When you cut a Copper wire in half it is example of what change?
Phisical
What would you indicate that a physical change takes place when copper is drawn into wire?
Copper is reshaped, but it's molecular structure does not change ;)
What would indicate that. Physical change takes place when copper is drawn into wire?
Copper is reshaped, but it’s molecular structure does not change.
What happens with a copper wire and a Bunsen burner equation?
When a copper wire is heated with a Bunsen burner, it undergoes oxidation as it reacts with oxygen in the air, forming copper(II) oxide (CuO) on its surface. The balanced chemical equation for this reaction is: 2Cu + O2 -> 2CuO.
Is drawing cooper into wire a chemical change?
No, drawing copper into wire is a physical change because the chemical composition of copper remains the same throughout the process. The transformation involves only a change in shape and size, not in the chemical properties of the copper atoms.
