Have a look at this video:
The cat turns into their teacher! This is magical because of many reasons, but one thing is that the woman is much bigger than the class. She has much more mass. In real life, mass does not change in a chemical reaction. The mass of the reactants are the same as the mass of the products.
We talked about what this means when it comes to chemical equations: the number of atoms in the reactants is equal to the number of atoms in the products.
This means we have to adjust chemical equations to make them balanced. I showed some examples and a method of how to balance them.
