We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first...

Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to...

By the end of this learning object, the student will be able to: Explain the meaning of salts and their properties.14004

This video covers the following<br/>
- The difference between a normal reaction and a reversib<br/>le reaction
- What is <br/>meant by 'equilibrium'
- What is meant by the 'position of equilibrium'

This is a lecture presentation on diffusion, where the process of diffusion of particles in liquids or gases is explained in terms of kinetic particle theory. The presentation incorporates a mixture of two liquids and a demonstration...

This video explains the concept of reversible chemical reactions. It starts by introducing reversible reactions and providing an example of the reaction between ammonium chloride, ammonia, and hydrogen chloride. The video then explains...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

Learn about reversible reactions. Find out where you can find them and what they actually are. In this lesson, we will learn about reversible reactions. When we fry an egg, it is impossible to 'unfry' it. A lot of reactions work in the...

The video explains the concepts of reversible reactions and dynamic equilibria in chemistry. The video also discusses how changing the temperature, pressure, or concentration of a system can affect the position of the equilibrium.

It explains separation of solid-solid mixture by using two methods, namely sublimation and evaporation.

Trainee teacher Emma Bradley is shown a series of nine quick-fire exo- and endo-thermic reactions by Dr Kay Stephenson from the Royal Society of Chemistry and Simon Quinnell of the National Science Learning Centre, York. The...
