Chemistry - Unit 3: Chemical Reactions


*Remember - Students are responsible for ALL classwork, homework, labs, notes, quizes, and tests. Regardless if a student is absent, late, at the nurse, on a fieldtrip, or for any other reason... students are still responsible for all work during the time/days that they missed class. Homework is due at the BEGINNING of class. I am usually available before school, during lunch, and after school (except Tuesdays) if a student needs to take a quiz, take a test, do a lab, or ask questions.

In Class Assignment for - Honors Mon 5/2 --- 4A Mon 5/2 --- B-Day Thur 5/5
1) Packet of worksheets on balancing equations Balancing Equations and Types of Reactions Intro.docx (NOTE: after you balance the equations, you also need to indentify the type of reaction and give the names of compounds). Below are several links for practicing how to balance equations. You will need to have completed section 8.2 in order to complete this assignment.
2) I encourage students to "work together" to solve these questions. Working together means that each student gets an answer, then you compare answers. Working together does not mean COPYING in any way (Working, not COPYING!!!).
