If it is just heated, the reaction is physical. If there is burning in the process, than the state of the copper will change, making it a chemical reaction.
The reaction between aluminum and copper chloride is a chemical change. During the reaction, a chemical reaction occurs resulting in the formation of new substances with different properties than the original reactants. This is different from a physical change where substances maintain their original properties.
The reaction of copper with acid is a chemical change because new substances are formed after the reaction takes place. Copper reacts with acid to form copper ions and hydrogen gas, which are different from the original copper and acid.
When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.
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.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
The reaction between aluminum and copper chloride is a chemical change. During the reaction, a chemical reaction occurs resulting in the formation of new substances with different properties than the original reactants. This is different from a physical change where substances maintain their original properties.
Yes, this is a chemical reaction.
The reaction of copper with acid is a chemical change because new substances are formed after the reaction takes place. Copper reacts with acid to form copper ions and hydrogen gas, which are different from the original copper and acid.
its a physical change
This is a physical change. Although you could say that the copper atoms are all moving around each other and changing which other atoms they are bonded to, you haven't reacted two substances to produce a different compound, so no chemical reaction. No reaction, ergo not a chemical change.
When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.
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 its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
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.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
