While it is certainly enticing when a company or individual claims that they have developed technology that can power cars purely on the water when it comes to science, there is a fundamental restriction to this very idea. Simply put,...

We use electrolysis to break water molecules down into hydrogen and oxygen. This is done using the Hoffman apparatus. Water is added to the apparatus along with some dilute sulfuric acid. When a current is passed through the water,...

What are alkali metals? Why are they so reactive? What are the trends as you go down the group? How do they react with water, oxygen and chlorine? Learn all this and more!

The video discusses the conservation of mass in chemical reactions and the application of this principle in calculating the mass of reactants and products. It also explores the features of chemical equations such as balancing and state...

The video explains how to calculate energy changes in chemical reactions by considering the energy required to break bonds and the energy released when bonds are formed. The video also introduces the concept of bond energy, which is the...

Bacteria of the human intestinal microbiome generate hydrogen gas (H2). Hydrogen gas is used by these same bacteria for methanogenesis, a biochemical pathway which generates methane. Here, we will discuss this process.<br/>

The archery contest has a long list of rules, but Chelsea the Cheater keeps breaking them! How does this affect the outcome (conclusion) of the competition? This lesson will begin our analysis of validity by examining the importance of...

This video explains the three main types of reactions that metals undergo: reactions with oxygen, reactions with acids, and reactions with water. The video provides word equations and examples of each type of reaction and notes any...

This nugget explains classification of hydrides into ionic, covalent and metallic.

It's time to start our survey of the periodic table, and we are going to start with just one element, hydrogen. This is the most abundant element in the universe by a wide margin. What does it do? What are its properties? What are its...

This video is on moles and how to convert between grams and moles. The speaker explains what a mole is, its significance in measuring chemical amounts, and the use of Avogadro's constant in determining the number of atoms or molecules in...

How to distinguish radio waves from space compared to man-made ones? What are some maintenance tasks that help the VLA work properly? What kind of upgrades has the VLA had of recent?<br/>

It explains preparation of Dihydrogen by Laboratory Method & Commercial Production

Learn the basics about what an element is, how a mixture is done and what a compound is. Find out in this video!

This is a video discussing the reactions of acids and metals, and deriving the associated ionic equations. The video covers how different acids produce different salts when reacting with metals, and how to predict the resulting salt....

It explains acids and bases in a laboratory. It explains reaction of acids and bases with metals, metal carbonates and metal hydrogen carbonates.

Methanogenesis: Intestinal Biosynthesis of Methane

This is a video discussing the theory and practical applications of electrolysis of aqueous solutions. The speaker explains what electrolysis is and how it involves the splitting of compounds using electricity. They then dive into the...

In this video, we do a Hess’s law example problem.
