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.
1. Assigning Oxidation Numbers to Elements in a Chemical Formula
Learn the importance of oxidation in chemical reactions. Discover the rules for assigning oxidation numbers in both covalent compounds and ionic compounds. Learn how to assign the oxidation number for each element in a chemical formula.
2. Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents
Learn how to identify an oxidizing agent and a reducing agent and how the loss or gain of electrons applies to each one. Learn the relationship between an oxidized or reduced substance and the oxidizing or reducing agent associated with it. Discover what steps to take to balance a redox reaction.
3. The Activity Series: Predicting Products of Single Displacement Reactions
Discover what a single replacement reaction is and how to identify it. Learn what chemical activity is, how that applies to an activity series table and how to predict the product of a single replacement reaction by referring to the activity series.
4. Electrochemical Cells and Electrochemistry
Learn to identify the parts of and be able to describe an electrochemical cell, including the electrolyte, electrodes, anodes, and cathodes. Learn how to make a homemade lemon battery and how to diagram an electrochemical cell that will light a light bulb.
5. Cathode and Anode Half-Cell Reactions
Learn how to write electrode half-reactions for cathodes and anodes. Discover how to calculate cell voltage potential when given a table of standard electrode potentials. Learn how to prevent corrosion using redox concepts and how to protect metal by cathodic protection.
