Do you think the copper and zinc underwent a physical change or a chemical change?

I'm sorry but my crystal isn't working tonight. If you told me what you did and what you observed I could help.

To determine whether the copper and zinc underwent a physical change or a chemical change, we need to understand the differences between these two types of changes.

A physical change refers to a change in the physical properties of a substance without altering its chemical composition. In other words, the substance remains the same in terms of its chemical identity. Examples of physical changes include changes in state (e.g., solid to liquid) or changes in shape or size.

On the other hand, a chemical change refers to a process that results in the formation of new substances with different chemical properties. During a chemical change, the atoms rearrange themselves, forming new chemical bonds. Examples of chemical changes include combustion, rusting, or any chemical reaction where the substances involved are transformed into different molecules.

In the case of copper and zinc, if they simply mixed together without undergoing any chemical reaction, it would be a physical change. However, if they reacted chemically to form a compound or any other new substance, it would be a chemical change.

To determine which change occurred, we would need more information. If copper and zinc were physically mixed together without any chemical reaction, it would be a physical change. But if they were exposed to a reactive substance like an acid or heat, resulting in the formation of a compound, such as copper(II) sulfate or zinc oxide, it would be a chemical change.

Therefore, to definitively answer whether the copper and zinc underwent a physical change or a chemical change, it would depend on the specific conditions and reactions they were exposed to.
