Question

copper compound burns physical or chemical property or physical or chemical change

Answer 1

When a copper compound burns, it undergoes a **chemical change**. Burning typically involves a reaction with oxygen (combustion), which alters the chemical composition of the substance. For example, if copper(II) sulfate is heated, it decomposes into copper(II) oxide and sulfur trioxide, resulting in a new substance being formed. Thus, the process of burning a copper compound is indicative of a chemical change rather than a physical property or physical change.
