Types of Chemical Reactions 11/12

Summary: This week in class we learned about the different types of chemical reactions. The four basic chemical reactions that can occur are: Synthesis reaction. Decomposition reaction, Single-Displacement reaction, and Double-Displacement reaction. A Synthesis reaction is a chemical reaction where two reactants make a product. A Decomposition reaction happens when a single reactant makes two products each apart of the first reactant.  A Single-Displacement reaction is when one chemical in a formula switches with another element in the product. A Double-Displacement reaction is when 4 elements switch (2 Non-Metals and 2 Metals) for the product.

SP5: Using mathematics and computational thinking
This week in class we used  math calculations to balance equations then figure out what type of chemical reaction was going on. Some math-related things that we had to pay attention to were: How many of each element were in the equation, Where was each element in the equation, How did each element move from reactant to product.

Balancing Equations 11/05

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.
