Balancing Equations 11/05

http://slideplayer.com/slide/9303062/

Summary: This week in class we learned about balancing equations. When you balance equations in chemistry, you have to remember the Law of Conservation of Mass. The  Law of Conservation of mass is a law that states when balancing equations no matter is created or destroyed. That means you cannot add any more elements or subscripts. You have to make all the atoms on each side of the equation equal by just using coefficients.

SP5: Using mathematics and computational thinking
This week in class we used mathematical thinking by: taking chemical equations and adding coefficients to them to make each side equal. Coefficients and non-subscript numbers that you put in a chemical equation to multiply certain: elements, compounds, and molecules. If there is a subscript after an atom then the coefficient multiplies by that number instead of multiplying itself be one if there is no subscript next to the element.
