ONLY 17 DAYS OF SCHOOL LEFT!!!

We checked in the homework (3 worksheet pages)

Mrs. Friedmann didn't finish grading the tests yet.

Today in class...

• Checked in homework
• We learned how to balance redox- equations
• The lesson is recorded and going to be posted by 9 tonight on Moodle. 

Balancing Redox Equations in Acid

• Redox can happen in either acid or base
• Acids have H+ and bases have OH-

In acids Steps:

      1.  Split equation into 2 half-reactions

      2.  Balance each half reaction:     

• Balance all atoms Other than H & O
• Balance oxygen using water
• balance hydrogen using H+
• Balance charges using electrons 

      3.  Multiply each half reaction by an integer so electrons for both half reactions are the same

      4. Cancel and Combine.

***There are 2 examples in the video(in the hw), but its too hard to type it out!!!***

Homework:

1) Forming Ionic compounds worksheet

2) Balancing Redox equations worksheet #1-8
