In this video we'll look at:

- Some examples of reactions that happen at different
rates
- The different ways we can calculate the rate of
a reaction
- Some examples of calculating the rate of reaction using decimetres...

In this video we cover: - Oxidation and reduction in terms of oxygen and electrons - Redox reactions - Displacement reactions - Ionic equations - Half equations This video is suitable for: - Higher tier only - All exam boards - Triple...

This video covers how acid react with different types of bases - metal oxides, metal hydroxides, and metal carbonates. It also covers the practical technique of how to make soluble salts from an insoluble base.

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!

This video covers: - Collision theory, and how it relates to the rate of reaction - The effect of temperature - The effect of concentration and pressure - The effect of surface area - The effect of catalysts

A simple explainer video about allergies. We explain how allergies occur, common causes and symptoms of allergies, how they are diagnosed and treated, and the most severe form of allergic reaction: anaphylaxis. We hope this video...

You’ve probably heard of the Maillard reaction, but here's how it actually works (AND how to hack it).

Dr. Forrester explains that materials in simple mixtures can be separated because they have different properties. She teaches that combining two or more substances can make new materials with different properties. She also identifies...

This video explores five fun facts about chemical reactions.

French and Raven identified those five bases of power as coercive, reward, legitimate, referent, and expert.

This video offers a more in depth look at how nuclear fusion occurs in the Sun.

Endothermic and Exothermic Reactions investigates heat-generating reactions and heat-consuming reactions by defining exothermic and endothermic.

Cellular Respiration analyzes the process of cellular respiration by describing how cells and organisms acquire and release energy.

"Understanding Chemical Reactions” uses a real-life example of a chemical reaction to explore how chemical changes occur and what they produce.

Yes, fire can burn without oxygen. While oxygen is an important oxidizing agent for combustion, it is not the only one. There are alternative oxidizers such as chlorine, fluorine, and bromine that can also support burning. Furthermore,...

Professor Dave explains the science and theory behind pericyclic reactions (Part One)

This video is answering the question of what is a star.

An introduction to retrosynthetic analysis.

An introduction to the Wittig reaction.

In this video I discuss "What is chemical engineering?" To put simply, in chemical engineering you design processes to transport, transform, and produce materials. Chemical engineering is much more than just...

Professor Dave explains the science and theory behind pericyclic reactions (Part Four)

With the Passerini and Ugi reactions down, let's learn one more multi-component reaction, the Biginelli reaction. Developed by Pietro Biginelli in 1891, this reaction produces pyrimidine derivatives. What's the mechanism? What are the...

I've been pouring 7 different metals into a 24" tall aquarium over the weekend, and the results have been super cool! I poured metals with different melting points to see if they had any different effects when they came in...

The inside of a pumpkin has a pretty interesting geometry. I had the idea to cast the inside to see what it looks like, but the inside of the pumpkin is very fragile and the 1000 degree aluminum pretty much destroys it as soon as it...
