Not all chemical reactions propel rockets into space. Energy needed to cook food comes from a combustion reaction. A combustion reaction is just one type of chemical reaction that you may recall from your previous science studies. What other types of reactions can you recall?
The focus of this lesson is to review how to write balanced chemical equations and to discover what balancing means in terms of the quantities of substances involved in a chemical process. The concepts covered in this lesson are critical to what you will learn in the remaining lessons of this module.
Essential Questions
- What information about a chemical system is contained within a balanced chemical equation?
- What information about a chemical system is not contained within a balanced chemical equation?
-
What is conservation of mass, and how is it demonstrated in a chemical equation?
Module 6: Lesson 1 Assignment
Save a copy of the Module 6: Lesson 1 Assignment to your course folder. You will receive more information about how to complete this assignment later in this lesson.
In this lesson you will also begin work on Module Assessment (Part 1)—Stoichiometry Calculator. What you develop in this lesson is the first part of a cumulative assessment for this module. You will submit the work you complete in this lesson to your teacher for feedback, and you will have the opportunity to revise and add to your Stoichiometry Calculator in the other lessons. Remember to keep a copy of your Stoichiometry Calculator in your course folder so you can revise it as you work through this module.
The other questions in this lesson are not marked by the teacher; however, you should still answer these questions. The Self-Check and Try This questions are placed in this lesson to help you review important information and build key concepts that may be applied in future lessons.
After a discussion with your teacher, you must decide what to do with the questions that are not part of your assignment. For example, you may decide to submit to your teacher the responses to Try This questions that are not marked. You should record the answer to all the questions in this lesson and place those answers in your course folder.
