Is the reaction between aluminum and copper chloride a physical or 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.
Is the reaction of copper and acid a chemical or physical change?
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.
Physical change copper chloride aluminum foil experiment?
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.
Does copper turn green by a chemical or physical change?
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.
Is putting a penny in lemon juice a physical or 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.
Is the reactivity of copper with oxygen considered a chemical or physical property?
The correct spelling is "reaction of copper with...' 1. Chemical reactivity is a chemical property. 2. A chemical reaction involve a chemical change.
Is the reaction between aluminum and copper chloride a physical or 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.
Is copper sulfate CuSO4 plus iron Fe a physical or chemical change?
Yes, this is a chemical reaction.
Is the reaction of copper and acid a chemical or physical change?
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.
Is copper a physical or chemical change?
its a physical change
Is cutting a copper wire a chemical or 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.
Physical change copper chloride aluminum foil experiment?
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 sulfate and sodium carbonate physical or 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.
Is the Statue of Liberty a physical change or 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.
Does copper turn green by a chemical or physical change?
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.
Is putting a penny in lemon juice a physical or 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.
A sheet of copper can be pounded into a bowl a physical or chemical change?
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.
