In this video from our Chemical Calculation Series learn how to calculate Percentage Mass within a Chemical Formula.

We get energy by eating other organisms, but plants don't have to do that. They can build their own food out of water, carbon dioxide, and sunlight. I'm sure you've heard of photosynthesis before, but let's take a look at some of the...

Paramagnetism and Molar Susceptibility

Why is desalinated water important? How can graphene help with desalination?<br/>
Properties Of Water, Part 4

We've learned a lot about DNA, but sometimes the representations of DNA that we use to talk about it are not especially accurate. Everyone knows the popular image with the ladder rungs, but let's really get in there and visualize DNA in...

Learn the basics about Empirical formulae from percentage composition. What is an empirical formulae? How do you calculate a percentage composition? Find out more in this video!

Learn the basics about the chemical compound Benzene and its properties? Find out in this video!

Learn the basics about the properties and chemistry of benzene, as a part of organic chemistry. Benzene is an organic molecule. Benzene is a colourless liquid at room temperature. Its boiling point is 80 degrees C. It’s found naturally...

In this video we will looks at what allotropes are, and different examples of them. The term allotrope refers to different forms of the same element. Diamond and graphite are made of only carbon atoms – yet they exhibit very different...

Learn the basics about alcohols and what they are.

Learn the basics about Alkanes and Alkenes, what are their properties, similarities and differences? Found out more in this video!

This is a chemistry video that discusses the reactions of alkenes. The video explains how alkenes have a carbon-carbon double bond as a common functional group, and therefore they react in a similar way. The video goes on to explain the...

In this video we will look at covalent bonds in methane, ammonia, water and hydrogen fluoride. They are small, covalently-bonded molecules. The atoms within them share electrons because they have half full or more than half full valence...

Naming molecules according to IUPAC nomenclature.

In this video learn how fractional distillation separates crude oil into useful fractions, examples of these fractions and where they're used in everyday life.

Defining stereochemistry and enantiomeric relationships.

Learn the basics of alkanes and alkenes. After watching the covalent bonds video you should have sufficient knowledge to understand about how alkanes and alkenes are formed and the differences between them.

Naming molecules according to IUPAC nomenclature.

Identifying Regions of Molecule with Resonance

Now that we know about simple sugars, we need to know about how these polymerize to form long polysaccharide chains, like cellulose, starch, and glycogen. Check it out!

The video explains the concept of homologous series in organic chemistry and provides detailed information about two important homologous series, alcohols and carboxylic acids. It describes the functional group present in each of these...

Alright, let's be real. Nobody understands molecular orbitals when they first take chemistry. You just pretend you do, and then in your next course you learn them a little better. And then a little better than that. And five years later...

Yes, I know moles are adorable furry creatures. This is a different kind of mole! A numerical mole. And we need to understand them to be able to make predictions about reactions. Let Professor Dave take you through the finer points.

Different forms of the same molecule are known as structural isomers; they have the same molecular formula but are different 'shapes'. In this video we will look at some different structures of butane - so they all have 4 carbons but...
