You put to chemicals in a bottle and screw on the lid.when you shake in the bottle starts to warm up what kind of reaction is this?

That experiment it's called a MRE bomb. That's why when you add the water to the chemicals in the bottle, it heats up causing the gasses to expand and then the bottle explodes. (It is a very dangerous experiment)

Hope I helped!
