Module 6—Stoichiometry

Reflect and Connect

 

Module Assessment (Part 2)—Stoichiometry Calculator

 

Did you recently modify the Stoichiometry Calculator based on the comments from your teacher? Retrieve the latest version from your course folder. Now that you have learned to perform stoichiometric calculations with masses, modify your Stoichiometry Calculator to complete calculations involving masses as well as moles. Also, do not forget to update the instructions that accompany your Stoichiometry Calculator.

 

Submit the updated electronic version of your Stoichiometry Calculator and instructions to your teacher for feedback. As in the previous lesson, you will be allowed to modify your Stoichiometry Calculator using the feedback you get from your teacher. Remember to keep a copy of your Stoichiometry Calculator in your course folder so you can revise it as you work through this module.

 

Reflect on the Big Picture

At the beginning of this lesson you examined how using appropriate quantities of hydrogen and oxygen can affect the products and usefulness of a chemical reaction. Knowledge of stoichiometry allows you to use appropriate quantities of reactants in order to maintain safety in many situations.

 

Discuss
 

Describe a situation where knowledge of stoichiometry is required. The situation you describe may be an industrial, commercial, or household process.

 

For your description, ensure that you properly cite any sources of information you use. Post your description to the discussion board. Read the descriptions of two other students. Provide comments on how to improve the clarity of the descriptions you read. You may revise your description using the comments provided by other students. Place a final copy of your description in your course folder and send a copy to your teacher.
