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 copper in a Bunsen burner a physical or chemical change?
Using a Bunsen burner to heat copper is a physical change. The copper undergoes a change in its physical state from solid to liquid without changing its chemical composition.
Is copper powder advisable to directly over the Bunsen burner?
No, it is not advisable to place copper powder directly over a Bunsen burner as it can lead to a rapid and uncontrolled reaction. Instead, it is recommended to use appropriate equipment and methods for heating copper powder safely.
When you heat copper sulphate with Bunsen burner?
Heating copper sulfate with a Bunsen burner will cause the compound to undergo a dehydration reaction, where it loses water molecules to form anhydrous copper sulfate. The characteristic blue color of the copper sulfate will change as it loses water molecules and turns white.
How can a Bunsen burner burn the copper metal?
A Bunsen burner can burn copper metal by providing a flame with high enough temperature to heat the copper to its ignition point, initiating a chemical reaction between the copper and oxygen in the air that produces copper oxide and heat. The heat generated from the Bunsen burner sustains the reaction, allowing the copper to continue to burn until it is fully consumed.

How do you use a Bunsen burner to kindle the copper metal?
You open th Bunsen burner. Then you use a metal grabber to grab the copper metal and put it on top of the Bunsen burner's flame. Soon the cooper metal will be kindled.

How do you make a compound with copper and sulfur?
copper sulphate?heat together in an evaporating basin on a gauze above a Bunsen burner and stir maybe?
What is the apparatus for heating copper metal?
To heat copper metal, you can use a Bunsen burner, a propane torch, or an electric hot plate. These apparatus provide a controlled source of heat to raise the temperature of the copper metal for various experiments or applications. Always follow safety precautions when working with heat sources.
What happens when you heat copper sulphate over a Bunsen burner?
I think it becomes a black liquid which, when it cools becomes a black powder. it also bubbles and gives off a gas (oxygen I think) that means that the copper sulfate had the oxygen removed making it copper sulfide. (I'm not entirely sure but this is what happened in the practical. Cheers.
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.
Why does a coppper gauze stop the flame on a Bunsen burner?
Copper gauze stops the flame on a Bunsen burner by dispersing the heat across its surface quickly, lowering the temperature and preventing combustion. This prevents the flame from igniting any flammable gases that may be present in the laboratory.
A sample of copper powder is heated in an evaporating dish using a Bunsen burner. If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.
