When metals react they lose their outermost electrons. This video covers which metals are the most and least reactive & also how we can determine reactivity by reacting them with acids and water. Then at the end we cover displacement...

This brief video tutorial briefly discusses resting membrane potential: 0:00​​. Introduction 0:53. What is a resting membrane potential? 1:33. How is a RMP measured? 4:12. How do we get a RMP at cell membranes? 9:04. How is the RMP...

The video discusses common chemical reactions involving metals such as oxidation and reduction, the formation of positive ions, and redox reactions. It also shows the results of experiments where different metals react with water and...

The video gives a brief overview of oxidation and reduction and then focuses on reactions at the cathode and anode in an electrolytic cell. The concept of half equations is introduced and demonstrated through examples, with a focus on...

This video is an educational presentation on common tests used to detect the presence of particular ions in compounds. The presenter demonstrates and explains various tests for positive and negative ions, including the flame test and...

Learn the basics about testing for negative ions. Which methods and techniques are used to test negative ions? Find out more in this video!

In this video, we explore the biochemical events that take place during the action potential of an individual cardiomyocyte.

This is a video lesson on metals and nonmetals. The speaker explains the differences between metals and nonmetals, their characteristics, how to identify them on the periodic table, and how to identify them through their reactions with...

Electrolysis is electrical current flow through a liquid which causes chemical changes. The liquid can be a molten ionic compound or aqueous solution. The liquid will contain free-flowing positive ions and negative ions. The positive...
