Is copper sulphate a physical change?
Copper sulfate dissolving in water is a physical change because the chemical composition of copper sulfate remains the same. Physical changes do not alter the chemical structure of a substance.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Is forming a bar of copper into a wire chemical or physical change?
Physical. It is simply changing the shape or configuration of solid copper to another shape. Chemical changes cannot be reversed.
Is copper sulfate a physical or chemical change when heated?
Thermal decomposition and loss of water are chemical changes.
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 copper sulphate a physical change?
Copper sulfate dissolving in water is a physical change because the chemical composition of copper sulfate remains the same. Physical changes do not alter the chemical structure of a substance.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Does copper sulphate undergo any physical or chemical changes during heating?
When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Copper wire is bent is physical or chemical?
Bending a copper wire is a physical change because the copper itself does not undergo a chemical reaction. The arrangement of copper atoms simply changes temporarily when the wire is bent, but the properties of copper remain the same.
Is forming a bar of copper into a wire chemical or physical change?
Physical. It is simply changing the shape or configuration of solid copper to another shape. Chemical changes cannot be reversed.
When copper turns green when exposed to air a physical or chemical change?
When copper turns green upon exposure to air, it undergoes a chemical change. This process occurs due to the reaction of copper with oxygen and moisture in the environment, forming copper carbonate and other compounds, commonly referred to as patina. Unlike physical changes, which do not alter the substance's chemical identity, this transformation changes the composition of the material.
Does copper have chemical or physical?
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
Is copper sulfate a physical or chemical change when heated?
Thermal decomposition and loss of water are chemical changes.
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.
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.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
