It is a reversible chemical change. Hydrogen and oxygen can be easily reacted to produce water - and if you're REALLY good at trapping the H2 and O2 molecules that form when you separate the water, you can produce as much water as you started with. There are a few other reactions that are reversible - NaOH + HCl comes to mind, but please don't do it. Most reactions are irreversible; if you react rennet with milk to produce cheese curds, you can't turn the curds back into milk and rennet.
