When a piece of copper is heated in presence of air its weight?
When a piece of copper is heated in the presence of air, it can react with oxygen to form copper oxide. This can result in an increase in weight due to the addition of oxygen atoms from the air to the copper atoms.
How does heated copper remove oxygen from the air?
Heated copper acts as a catalyst in a chemical reaction where the oxygen molecules in the air are reduced to form copper oxide. This reaction effectively removes oxygen from the air by chemically binding it to the copper surface.
When copper is heated in air?
When copper is heated in air, it undergoes oxidation and forms copper oxide. Initially, a layer of black copper oxide (CuO) forms on the surface, and upon further heating, it turns into red copper oxide (Cu2O).
When copper is heated in air write chemical equation?
When copper is heated in air, it undergoes oxidation to form copper(II) oxide. The chemical equation for this process is: 2Cu(s) + O2(g) → 2CuO(s)
What is the name of the black stuff that shows on copper when heated?
The black stuff that forms on copper when heated is called copper oxide. It forms as a result of the copper reacting with oxygen in the air during the heating process.
How is copper obtained from it's sulphide ore write the balance chemical equation?
Copper is obtained from its sulfide ore by smelting, where the copper sulfide is heated in the presence of oxygen, producing copper metal and sulfur dioxide gas. The balanced chemical equation for the reaction is: 2Cu2S + 3O2 -> 2Cu + 2SO2
Why the colour of heated copper powder becomes black when air is passed over it?
When air is passed over heated copper powder, the copper undergoes oxidation, forming copper oxide. Copper oxide is black in color, which is why the heated copper powder appears black when air is passed over it.

What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
What is the name of the black stuff that shows on copper when heated?
The black stuff that forms on copper when heated is called copper oxide. It forms as a result of the copper reacting with oxygen in the air during the heating process.
What is the equation for copper heated in air?
When copper is heated in air, it reacts with oxygen to form copper oxide. The equation for this reaction is: 2Cu(s) + O2(g) -> 2CuO(s)
What two products are formed when iron sulphide is heated in air?
Solid iron oxide and a poisonous called sulphur dioxide
Why is the black stuff on heated copper not soot?
The black substance that forms on heated copper is not soot because copper does not undergo combustion in the same way as carbon-based materials. The black substance is most likely copper oxide, formed when the copper reacts with oxygen in the air.
What will happen when copper is heated?
When copper is heated, it will expand due to increased molecular motion. If the temperature is high enough, copper will eventually melt and turn into a liquid state. Copper can also undergo a chemical reaction with oxygen in the air, leading to the formation of copper oxide on its surface.
