Cell Potential & Gibbs Free Energy, Standard Reduction Potentials, Electrochemistry Problems Teacherflix 11 Views • 2 years ago

This chemistry video tutorial discusses the relationship between cell potential and gibbs free energy. It contains plenty of examples and chemistry practice problems. It discusses the signs of the potential energy and delta G in determining if a reaction is spontaneous or nonspontaneous. The system is in equilibrium whenever delta G and E is equal to zero. This video discusses Faraday's constant which relates the electric charge to moles of electrons per mole of substance. 1 volt is 1 Joule per coulomb. voltage is a measure of electrical potential energy per unit charge. delta G represents the maximum amount of electrical work that can be performed by a reaction. This tutorial contains problems where you have to find the value of n in order to use it in the equation delta G = -nFE. To find it, you need to balance the half reactions and make sure the moles of electrons are the same using the least common multiple rule. In addition, you need to calculate the cell potential of the net reaction using the standard reduction potential of the half reactions. This lesson is basically a section in electrochemistry.

Mutually Assured Destruction (Cold War -) Teacherflix 6 Views • 2 years ago

What does M.A.D. mean? M.A.D. refers to the full-scale use of nuclear weapons by two opposing sides, resulting in one clear, obvious outcome – mutually assured destruction. The policy of M.A.D. rests on the idea that if two countries or continents are equally as capable of destroying one another through nuclear attack, then there is no incentive for either side to pull the trigger, or remove it. Instead, nuclear-capable countries keep each other in check with the knowledge of the MAD doctrine, and that any sort of “first move” would result in global nuclear devastation.

Abbreviations for Kids | Learn some common abbreviations and why we shorten words Teacherflix 8 Views • 2 years ago

Do you know what an abbreviation is or how to make one? An abbreviation is a shortened form of a word or phrase. You can make one by taking letters out and replacing them with other letters or symbols, such as a period. In this video, you and your kids will learn about some common abbreviations, many of which you probably use every day.

One of the most common abbreviations has to do with the time of day. We use a.m. in the morning hours and p.m. in the evening and night hours. What do those actually stand for? "Ante meridiem" is Latin for before noon, so we use a.m. for all the times before noon. "Post meridiem" is Latin for after noon, so we use p.m. for all the times after noon.

Other common abbreviations involve days of the week, months of the year, measurement, and time. For example, we can write Sat. for Saturday or Dec. for December rather than writing out the whole word. In recipe books, you will often find abbreviations for their measurements, like tsp for teaspoon or oz for ounce. And you've probably seen abbreviations like min for minutes or yr for year.

We hope you and your student(s) enjoyed learning about abbreviations! If you want even more practice, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

Cardinal Directions for Kids | What are cardinal directions? | North, south, east, and west Teacherflix 10 Views • 2 years ago

What are Cardinal Directions? In this video built as an introduction to kids we will learn all about the 4 Cardinal Directions which are: North, South, East, West. Each time you go somewhere, you travel or move in a direction, which is the course or path you move in. You might walk down the street and then turn right or left, later turn around and return home. You are moving in different directions throughout the day. In the same way, cars, airplanes, buses, trains, and other vehicles move in different directions too. However, instead of turning to the right or left, or traveling up or down the
street, there are special words used to name the directions a vehicle or person can travel.

There are four main directions or points called cardinal directions (sometimes cardinal points). The four points include north (N), east (E), south (S), and west (W). The direction words are found on maps, compasses, street signs, and in many other places. The cardinal directions help people travel from place to place. In this video you'll learn it all and even have a chance to practice what you learn at the end.

To enhance your child's learning we invite you to visit us at https://learnbright.org/lesson....s/social-studies/car to download a free 10-page lesson plan with cardinal directions worksheets, activities, and even more fun content.
