Stoichiometry

 

 

Unit Overview: For students to learn the process and understand stoichiometry. They will understand how mole ratio relates to chemical equations. The students will be able to balance a chemical equation and then use the balanced equations to find amounts of certain chemical compounds.

 

Personal Achievement: I think I learned a lot from this unit. I thought this chapter was going to be hard because of the weird chapter name. But it turned about to be really easy, even though I spend a decent time figuring out how to write the steps of solving the problem. I did well on the quiz and I show my work correctly. I realized that practice makes perfect.
Enduring Understanding: Chemical formula is the ratio of the elements. It is a way of expressing how many of each elements are there in the compound or molecules. It also represent the percent mass, which tells you about the concentration or the component of the mixture.

Strengths: Applies mathematical representations to stoichiometry. I am confident with this in the quiz and I show my work clearly and correctly.

 

Areas for Improvement: Understands and can apply a mole ratio to find the amount of a chemical compound. I feel like I should study more about mole because I don’t really know what it is. I just tried to understand the step of solving the problem but don’t really know what mole is and what it represents.

 

The picture below was when we did the Smore lab. The purpose of the lab was to explore the principle of stoichiometry. ‘Stoichio’ means element and ‘metry’ means the process of measuring. The mass and quantity relationships among reactants and products in a reaction are found using the process of stoichiometry. Also, we wanted to determine the limiting reactant in the synthesis of S’mores.
