It is a strange question to ask a 9 year old, not least because there isn't actually any one definitive answer you can give. There isn't even a simple answer to what an explosion is. (they come in many forms). Having said that -and ignoring nuclear explosions and other phenomenon such as balloons bursting - concentrating just on chemical explosions, II think the simplest answer your 9 year old could give would be: a chemist.
