Lesson on the antibiotic Metronidazole (Flagyl). Metronidazole is a small sized antibiotic, which allows it to be easily absorbed and diffusely distributed throughout the body. This makes it particularly important in bone and brain...

Welcome to our new video series called "New Economic Thinking." The series will feature dozens of conversations with leading economists on the most important issues facing economics and the global economy today.



This episode...

The video explains two processes involving atomic nuclei that release large amounts of energy - nuclear fission and nuclear fusion. The video explains how uranium 235 can be made to undergo nuclear fission and also discusses the concept...

It illustrates the method of balancing redox reactions using oxidation number method and half reaction method.

The Cannizzaro reaction is pretty old, over 150 years old in fact, but it is still an important reaction in organic chemistry. It involves the disproportionation of two equivalents of an aldehyde, meaning one is oxidized to the...

More enolate chemistry with the Robinson annulation.

An introduction to addition reactions.

Learn the basics about condensation polymerisation within the overall organic chemistry topic.

This video discusses mass changes in chemical reactions. The Law of Conservation of Mass is introduced, which states that atoms are not lost or gained during a chemical reaction. Two examples are given: the reaction of sodium with water...

This video explores five fun facts about droughts.

The video discusses the factors affecting dynamic equilibrium by explaining the difference between exothermic and endothermic reactions, and how they relate to reversible reactions. The concept of dynamic equilibrium is explained using...

Alkene Halogenation: Theory, Mechanism, Examples

Learn the basics about how to make insoluble salts as a part of the overall acids and bases topic.

The video explains how to use the masses of reactants and products in a chemical reaction to calculate the balancing numbers in a symbol equation. Two examples are provided to illustrate the process, and the concept of limiting reactants...

Here is one example in which we calculate enthalpy of reaction (ΔH_rxn).

This video begins with real world examples of heat transfer involving energy changes from chemical potential energy. The program shows exothermic reactions which occur such as a gasoline engine, wood on a campfire and athletes running....

In this video, we will discuss the mechanisms of different types of biochemical inhibitors, how to interpret their Michaelis-Menten plots, and their effects on Vmax and Km of enzymes.

Looking at anti-markovnikov hydrohalogenation as an example of a radical reaction.

This video provides an explanation of what a catalyst is and how it can increase the rate of chemical reactions. The concept of activation energy is introduced, and it is explained that catalysts lower activation energy, allowing more...

The video explores the production of ethanol and its various uses. It starts by discussing the importance of ethanol as a clean-burning fuel and a widely used industrial solvent. The video then explores different ways of producing...

This nugget explains the different chemical properties of carboxylic acids and their uses.

Let's Bounce! Reaction balls are an awesome addition to your gym that can teach hand-eye and reaction skills.

Learn the basics about the principle of green chemistry that considers reducing derivatives, as a part of environmental chemistry. Functional groups are the sites in a molecule where a reaction occurs. Some molecules may have more than...

Head of Science Alastair Gittner, sets up the lesson by asking his students to consider how railway tracks are joined together, using their knowledge of the reactivity series. The classic thermit reaction between iron oxide and...
