Understanding the Law of Conservation of Mass
The Law of Conservation of Mass is really important when we solve problems about chemical reactions.
This law says that mass can't be created or destroyed.
In other words, the total mass of what you start with (the reactants) is the same as the total mass of what you end up with (the products).
Balanced Equations:
Make sure your chemical equations are balanced.
This means that the number of atoms for each type of element should be the same on both sides of the equation.
For example, look at this reaction:
Here, we have two hydrogen (H) molecules and one oxygen (O) molecule reacting to make two water (H₂O) molecules.
Mole Ratios:
Use balanced equations to figure out mole ratios.
For example, if you have 4 moles of H₂ (hydrogen gas), you will need 2 moles of O₂ (oxygen gas) to make water.
By understanding this law, you can predict how much of each substance will be used or made in reactions.
This makes solving these problems easier and more accurate!
