Well, darling, casting silver in a mold is a physical change. Why? Because you're just changing the shape and form of the silver without altering its chemical composition. It's like getting a new haircut - you're still the same person, just with a different look.
Casting silver in a mold is a reversible physical change because the silver can be melted again and reshaped into a different form. The process does not alter the chemical composition of the silver.
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
Tarnishing of a silver spoon is a chemical change. It occurs when the silver reacts with sulfur compounds in the air or food, forming silver sulfide. This chemical reaction alters the composition of the spoon, resulting in the tarnished appearance.
The ring turning your finger green is a chemical change. This occurs when the silver reacts with substances like sweat or lotions on your skin, forming compounds that can discolor the metal and your skin. This change is not reversible by physical means.
The tarnishing of a silver surface is a chemical change. This is because the silver undergoes a reaction with sulfur compounds in the air, forming silver sulfide. This chemical reaction results in a change in the composition and properties of the silver surface.
Casting silver in a mold is a reversible physical change because the silver can be melted again and reshaped into a different form. The process does not alter the chemical composition of the silver.
