The bombardier beetle is able to shoot out a boiling liquid from its abdomen using an exothermic chemical reaction. It stores hydrogen peroxide in one compartment and hydroquinone in another, and when these two chemicals mix together along with a catalyst, the reaction creates gas pulses that propel the hot liquid outward for protection without harming the beetle. The reaction forms benzoquinone, water, and releases heat equal to the temperature of boiling water.

2. Exothermic Reaction
 The bombardier beetle have two different parts in
its body, one has hydrogen peroxide one has
hydroquinone. When they mix with each other
and a catalyst there is an exothermic reaction.
The mixture gets close to boiling point and it also
creats a gas that shoots out the mixutre in pulses
which allows it to not melt itself.
 Uses it for protection

3. Equation
 H2O2+C2H4(OH)2 C6H4O2+H2O
 3C2H4(OH)2+ 3H2O2 C6H4O2+10H20
