Computational Thinking in Science and Math
Lesson 8: Balancing Equations Continued
The Law of Conservation of Mass states: that mass is neither created nor destroyed in any chemical reaction. Therefore balancing equations requires the same number of atoms on both sides of a chemical reaction. The number of atoms in the reactants must equal the number of atoms in the products.
You will use molecular model kits to help you balance equations. You will begin by building reactants then disassembling them to build the products. If you have any atoms of the reactants left, you must go back and adjust the number of reactant molecules in such a way that none of the atoms are left over after you build the products.
After completing the activity you will be provided with basic notes on a preferred element order to balance equations.
