Ch 14: MEGA Chemistry: Redox Reactions & Electrochemistry

About This Chapter

Let us help you study for the MEGA Chemistry assessment by exploring redox reactions and electrochemistry. You can refresh your knowledge with engaging video lessons, and gauge your comprehension by taking short quizzes and a chapter exam.

MEGA Chemistry: Redox Reactions & Electrochemistry - Chapter Summary

This chapter offers a variety of resources you can use to enhance your preparations for the MEGA Chemistry assessment. Start by reviewing lessons that examine redox reactions and electrochemistry as you prepare to do the following on the exam:

  • Describe the importance of assigning oxidation numbers to elements in chemical formulas
  • Explain how to balance redox reactions and identify oxidizing agents
  • Define a single displacement reaction
  • Provide details about electrochemical cells
  • Detail how to write electrode half-reactions for cathodes and anodes

Video lessons in this chapter are short, averaging about 10 minutes each. Accessing condensed, yet comprehensive lessons helps streamline your studying process. You can further enhance your preparations by taking advantage of timelines with video tags that let you skip to key topics in the videos without watching them in full. If you need clarity on any lesson topic, feel free to submit your question to our experts.
