There are tens of thousands of different chemicals that exist, so there are endless reactions that can be created!! In nuclear the main ‘reaction’ that is used is fission of Uranium- this is where the nucleus of the Uranium atom splits apart and gives out energy that can be used to boil water, to turn a turbine and generate electricity!

Lots of different things can be used to perform chemical reactions, you just need to know how any two chemicals will behave when interacting with each other. But on a most basic level, pretty much everything is a chemical (including ourselves, we’re just made up of lots of different pretty complicated ones) and reactions happen all the time. For example, when we eat food, a chemical reaction happens in our body to turn that into energy so we can do all the things we need to like run around or do science all day. Likewise, a chemical reaction can also be things that you might see in a lab where a metal like sodium (Na) reacts really strongly with water to produce sodium hydroxide (NaOH) and hydrogen gas (H2), like this: https://www.youtube.com/watch?v=ODf_sPexS2Q

Anything really, everything is made up of different elements and they all react with things differently. For example, water reacts with iron and potassium differently, the potassium reaction is a lot more exciting than iron.

A chemical reaction is just a process where one or more substances are converted to different substances when they are brought together or external energy is applied (such as heat).
Here’s a chemical reaction you can do at home… take 2 eggs, 125 grams each of butter, sugar and self-raising flour and mix them in a bowl. Transfer into a baking dish and apply some heat (about 170 C) by putting it in the oven for 20-30 minutes.
Best chemical reaction I know!

I would say most of the material on earth can be used to create a chemical reaction, there are lots of interesting experiments that you can do on youtube
