In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is...

From turf toe to toxic Zamboni's, sports injuries aren't just for pro athletes.

In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.

Pupil outcome: I can use chemical symbols to write down chemical formulae for elements and compounds. Key learning points: - The symbols for each element (each type of atom) a substance contains, appear in its chemical formula. - Numbers...

Explores the minimal impact of inert gases on equilibrium, except in cases of volume change.

Explains how equilibrium shifts in response to pressure changes, following Le Chatelier’s Principle

Predict future air quality levels using LSTM models for a location of your choice to mitigate air pollution impact.

Combustion chemical reactions are reactions that burn a fuel. The fuel that is burned is a hydrocarbon and we all know that oxygen is needed for something to burn. So all combustion reactions will have the reactants of a hydrocarbon and...

Welcome to Tadashi Science! Join us as we simplify the world of science. In this video, we'll teach you how to balance combustion chemical reactions. Learn the difference between complete and incomplete combustion and discover why these...
