315 - How do chemical reactions create new substances?

Imagine building with Legos. In a chemical reaction, tiny particles called atoms are like the Lego blocks. When these blocks combine or break apart in a new way, they form a new substance.

Think of it like this:

1. We start with two or more Lego sets (the original substances).
2. The blocks get rearranged and connect in a new way (the chemical reaction happens).
3. A new Lego creation is formed (a new substance is created).

For example, when we mix baking soda and vinegar, they react and create a new substance called carbon dioxide gas. This is why we see bubbles and foam when they mix.

So, chemical reactions help create new substances by rearranging the tiny building blocks of atoms in a new way.
