What solid residue will turn from green to black if heated?
Copper(II) nitrate will turn from green to black when heated due to the decomposition of the compound. The green color is due to the presence of copper ions, which decompose into copper oxide when heated, resulting in the color change to black.
What is he pH of copper oxide?
Copper oxide itself does not have a defined pH because it is a solid compound and pH is a measure of the acidity or basicity of a liquid solution. However, when copper oxide is dissolved in water, it can form a slightly basic solution, with a pH typically around 7 to 9, depending on the concentration and specific form of copper oxide (such as cuprous oxide or cupric oxide).
Is copper a solid or liquid or gas?
It depends on the temperature, however, at standard and room temperature, copper is a solid.
What physical changes are in CuCO3?
Explanation: Copper(II) carbonate (solid), when heated, forms copper(II)oxide (solid) and carbon dioxide (gas). First, the formation of a gas is one hit this is a chemical change. The second hint, the chemical reaction cannot be reversed.
Chemical formula for copper II oxide?
The chemical formula for copper II oxide is CuO. It is a black solid compound where copper is in the +2 oxidation state.
What is the black solid formed when copper carbonate is heated?
This compound is the copper(II) oxide, CuO.
What is a blue solid that produces a black solid when heated?
Either sodium carbonate or copper carbonate
When copper is melted or boiled is it a solid liquid and gas?
sort of all of them, as when heated it can be a liquid or gas and when frozen it is a solid
What is copper metal heated with oxygen gives solid copper II oxide classified as?
This is a chemical reaction known as oxidation, where copper metal undergoes a reaction with oxygen to form a new compound, which is solid copper II oxide.
Is copper is liquid or gas?
at room temp it is a solid... but it can be made into a liquid or gas if heated as with anything,,, but naturally seen as a solid.
Can a copper zinc penny change state from solid to liquid?
Yes if it is heated.
Is copper a soild liquid or gas?
at room temp it is a solid... but it can be made into a liquid or gas if heated as with anything,,, but naturally seen as a solid.
Is copper oxide a solid?
Yes, copper(II) oxide is a solid at standard and room temperature. Copper(I) oxide is also a solid in these conditions as well.
What solid residue will turn from green to black if heated?
Copper(II) nitrate will turn from green to black when heated due to the decomposition of the compound. The green color is due to the presence of copper ions, which decompose into copper oxide when heated, resulting in the color change to black.
What happens when copper powder is heated?
When copper powder is heated, it undergoes a series of color changes as it oxidizes. Initially, it turns black as copper oxide forms on the surface, then it changes to a red-brown color as cupric oxide forms. Finally, at higher temperatures, it transforms into a black solid known as cupric oxide.
What is he pH of copper oxide?
Copper oxide itself does not have a defined pH because it is a solid compound and pH is a measure of the acidity or basicity of a liquid solution. However, when copper oxide is dissolved in water, it can form a slightly basic solution, with a pH typically around 7 to 9, depending on the concentration and specific form of copper oxide (such as cuprous oxide or cupric oxide).
What is the state of matter of copper II oxide at room temperature?
Copper II oxide is a solid at room temperature.
