The Law of Conservation of Mass says that during a chemical reaction, matter can't be made or destroyed.
This means that if you add up the total weight of the starting materials (called reactants) before the reaction, it will be the same as the total weight of the new materials (called products) after the reaction.
Why It Matters in Chemistry:
Balancing Equations: When we write chemical equations, we have to make sure the number of atoms for each element is the same on both sides of the equation.
In this equation, there are 4 hydrogen atoms and 2 oxygen atoms on both sides, which keeps everything balanced.
Predicting Reactions: Knowing about mass conservation helps us figure out how much of the products we will get and how much of the reactants we will need.
Overall, this law is very important for understanding how different substances work together and change during chemical reactions!
