This resource turns balancing equations challenge into a complete, ready to use review for Grade 9-12 chemistry, covering the same NGSS standard from three different angles.

Students will answer questions such as "Balance the equation: C₂H₅OH + O₂ → CO₂ + H₂O?", "What is the balanced equation for the reaction of sodium bicarbonate with acetic acid?", and "Balance the equation: Na + Cl₂ → NaCl?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 27 pages in total

All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.

Ways to Use This Resource

• First look diagnostic to plan your unit
• Bell ringers and warm ups during the unit
