It is a physical change because it has only changed state.
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
No, mixing sodium carbonate and copper sulfate is a physical change as the substances retain their chemical identities. A chemical change would involve a reaction where new substances are formed.
The compound you are referring to is copper carbonate, which has the chemical formula CuCO3. It is also known as copper(II) carbonate and is commonly found in nature as the mineral malachite.
No, it is not a chemical reaction. The added heat only drives the water molecules out of the crystal structure. No bonds are made or broken. Actually, it is a chemical change, because there are bonds between the water and CuSO4. by heating, these bonds are broken, there is a color change not coming from the reactant.
The change from green copper carbonate to black copper oxide is a chemical change because it involves a chemical reaction where the chemical composition of the substance is altered. The color change indicates a new substance has formed, making it a chemical change.
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
The chemical formula of copper (I) carbonate is Cu2CO3.
Yes, the green patina that forms on copper is a chemical change called oxidation. When copper reacts with oxygen and moisture in the air, it forms copper oxide and then copper carbonate, creating the green color seen on aged copper surfaces.
Heating copper carbonate causes it to decompose into copper oxide, carbon dioxide, and oxygen. When the carbon dioxide gas escapes, the overall mass of the compound decreases, resulting in a lower mass of copper carbonate after heating.
The chemical formula of copper (II) carbonate is CuCO3.
No, mixing sodium carbonate and copper sulfate is a physical change as the substances retain their chemical identities. A chemical change would involve a reaction where new substances are formed.
Heating copper sulfate causes a chemical change because it leads to the compound decomposing into different substances, namely copper oxide and sulfur dioxide. This change alters the chemical composition and properties of the original compound, indicating a chemical reaction has occurred.
The chemical formula of copper carbonate is considered to be Cu(OH)2CO3.
The compound you are referring to is copper carbonate, which has the chemical formula CuCO3. It is also known as copper(II) carbonate and is commonly found in nature as the mineral malachite.
Copper turns green due to a chemical reaction with oxygen and other elements in the environment, forming a layer of copper oxide and copper carbonate on the surface. This process is known as oxidation and is a chemical change.
Yes it is a chemical change Because colour is changing and a new substance is forming and it's irreversible.
