In this video Paul Andersen explains how Le Chatelier's Principle can be used to predict the effect of disturbances to equilibrium. When a reversible reaction is at equilibrium disturbances (in concentration, temperature, pressure,...

Burning a marshmallow can release more energy than detonating an equal mass of TNT...so why isn't a marshmallow as dangerous?

In this video Paul Andersen explains how disturbances to a reversible reaction at equilibrium affect the equilibrium constant and the reaction quotient. For example if the concentration is changed the reaction will move to reestablish...

In this video Paul Andersen explains how heat can be absorbed in endothermic or released in exothermic reactions. An energy diagram can be used to show energy movements in these reactions and temperature can be used to measure them...

In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the _G is less than zero the process is spontaneous. If the _G is greater than zero the...

Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by...

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...

SUMMARY

In this video, I show Why Some Reactions EXPLODE and Others COOL: Root Cause of Chemical EnergyI I show how the chemistry behind endothermic and exothermic reactions can be traced to the underlying quantum...

When wood comes in contact with fire, it undergoes thermal degradation, or pyrolysis. The pyrolysis of wood leads to the release of certain volatile gases and the formation of char, which eventually undergoes flaming and glowing...

We demonstrate an endothermic reaction by mixing hydrated barium hydroxide with ammonium thiocyanate. When these two solids react they take heat from the surrounding air. Chemistry - Reactions - Learning Points. Breaking bonds takes in...

We add a jelly baby to a boiling tube containing potassium chlorate. When the chemicals react, gas is rapidly produced. The screaming sound is created as the gas escapes from the tube. The sweet burns brightly as the reaction occurs....

Explore the concept of energy changes in chemical reactions, including exothermic and endothermic reactions. Learn how chemical reactions can either release or absorb energy in the form of heat or light, with examples ranging from...

In this video we cover :<br/>
- What exothermic and endothermic re<br/>actions are
- What reaction profiles ar<br/>e and how to draw them
- What activation energy is and how we show it on reaction profiles

When wood comes in contact with fire, it undergoes thermal degradation, or pyrolysis. The pyrolysis of wood leads to the release of certain volatile gases and the formation of char, which eventually undergoes flaming and glowing...

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

This video provides an overview of reaction profiles, explaining the concepts of exothermic and endothermic reactions, as well as activation energy. The presenter defines each of these terms, provides examples of each type of reaction,...

This video provides an introduction to reaction profiles and explains the concepts of exothermic and endothermic reactions, as well as activation energy. The speaker uses a graphical representation of the energy changes involved in...

How do we define the system? The surroundings? In this video, we explore this along with energy transfer between system and surroundings in the forms of heat and work. We also do a sample calculation of total energy (E = q + w).

It explains the application of first law in terms of work. It describes the isothermal and free expansion of an ideal gas, enthalpy,intensive and extensive properties.

What exactly is Le Chatelier's Principle? And why is it important to learn it to understand chemical reactions?

The video discusses how to measure entropy change in chemical reactions through an experiment using calorimetry. It explains the concepts of exothermic and endothermic reactions and how to calculate heat energy change. The equipment used...

The video discusses how diagrams of reaction profiles can be used to show the energy changes that occur during chemical reactions. It explains the concept of energy conservation in chemical reactions and how the transfer of energy to or...

The video is a lecture presentation on exothermic and endothermic reactions. The presenter explains the definitions of these reactions and demonstrates two experiments to determine whether a reaction is exothermic or endothermic. The...

This video explains the concept of cellular respiration and the differences between aerobic and anaerobic respiration. It explains the word and chemical symbol equations for aerobic and anaerobic respiration, as well as the differences...
