What causes a chemical change?
Chemical changes occur when a material combines with another to generate a new substance, a process known as chemical synthesis, or when a molecule decomposes into two or more separate chemicals, a process known as chemical decomposition. These processes are known as chemical reactions, and they are generally irreversible until they are followed by other chemical reactions.
Is rusting a chemical change?
A chemical change such as rusting is one example. A chemical property is a property that specifies a substance’s capacity to undergo a certain chemical transformation. Iron’s chemical feature is that it may combine with oxygen to generate iron oxide, which is the scientific term for rust.
