Cooper get oxidised to copper oxide when burned in air.
When copper is heated in oxygen, the compound formed is copper oxide.
When sodium is burned in chlorine gas, sodium chloride (NaCl) is formed. This is a white solid compound commonly known as table salt.
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
Metal is a category of elements but copper chloride is not an element. It is a compound made from chlorine and copper. Among these copper is a metal and chlorine is a non-metal.
Examples: compounds of copper, boron, barium
When copper is heated in oxygen, the compound formed is copper oxide.
Copper sulfide is the compound formed when copper reacts with sulfur. Depending on the ratio of copper to sulfur, different forms of copper sulfide can be formed, such as Cu2S and CuS.
Copper sulfate is a compound. It is formed by combining copper, sulfur, and oxygen atoms in specific ratios to create the compound CuSO4.
This compound is the iron(III) oxide, Fe2O3.
The new compound formed when magnesium is burned in air is magnesium oxide (MgO).
carbon dioxide
When copper is mixed with oxygen, copper oxide is formed. The specific compound formed depends on the ratio of copper to oxygen present during the reaction.
When sodium is burned in chlorine gas, sodium chloride (NaCl) is formed. This is a white solid compound commonly known as table salt.
Copper sulfate is the compound formed when copper, sulfur, and oxygen combine. The chemical formula for copper sulfate is CuSO4.
The compound CuCl is called copper(I) chloride. In this compound, copper has a +1 oxidation state, and it is formed by the combination of copper and chlorine. Copper can also form a +2 oxidation state, leading to another compound called copper(II) chloride (CuCl₂).
The chemical formula for the compound formed by the reaction of copper(II) ions with thiocyanate ions is CuSCN.
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
