What is the difference between a chemical change and a chemical reaction??
My answer: A chemical change leads to a solidifed chemical reaction but more or less they are the same thing because it's a change in which one or more pure substances are converted into diffeent pure substances with different properties.
I don't know how to differentiate the.

It a different kind of question which I've never seen before and it's a little tough. A chemical reaction involves either a decomposition of one material to different materials or a combination of one material with another. This process is a chemical reaction and in this process each material undergoes a chemical change since each material formed is chemically different from how it started.
