Okay kiddo, so hydrazoic acid is a really strong and dangerous acid made up of three different atoms – nitrogen, hydrogen, and oxygen.
It's a bit like when you mix vinegar and baking soda together – it creates a reaction that makes a fizzy and bubbly mixture. But hydrazoic acid is much stronger and can be really dangerous if you touch it or breathe it in.
In fact, it's so dangerous that it's often used in things like explosives or as a poison! But don't worry, because it's also used in some good things too, like in medicine to help treat some diseases.
Scientists have to be really careful when they work with hydrazoic acid because they have to make sure they stay safe and don't get hurt. So even though it might seem interesting, it's not something you should play with at home or anywhere else!
