This video provides an explanation on how to balance chemical equations using examples of simple word equations. It explains the importance of multipliers and subscripts in chemical equations and demonstrates how to use them to balance...

Chemical equation shows the overall chemical change of reactants into products. It's a bit like a detailed cooking recipe, but where all the ingredients and all the products are written down, even the ones you can't necessarily see. The...

Sometimes we want to talk about chemistry without using fancy symbols, just with words. Shouldn't we be able to do that? Yes, we should! Here's how.

The video is a lecture presentation on the topic of neutralization and salt production. The presenter discusses the reactions between acids and bases, and demonstrates examples of reactions between different types of acids and bases,...

This video explains the three main types of reactions that metals undergo: reactions with oxygen, reactions with acids, and reactions with water. The video provides word equations and examples of each type of reaction and notes any...

Holy spectroscopy! 100 First Words for Little Geniuses is the perfect book for aspiring geniuses everywhere. Forget starting with words like banana or ball. Why not start with words like inertia, electron, Bunsen burner, or...

In this video, we work examples of exponential growth and decay regarding colonies of bacteria and radioactive decay. We will find the "k" value, and solve for it using logarithms. These exponential word problems are very similar to...

Heisenberg’s uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

Heisenbergs uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used...

In this video we look at how to derive equations and expressions from sentences. We can write ‘c’ minus 5 in symbols rather than words: c - 5. And d times 4: 4d. But we can do much more than this. We can actually turn sentences into...

In this video Paul Andersen explains how the reaction path can be described in an energy profile. Enough energy must be added to reach the activation energy required and stress the bonds. Eventually the bonds break and new bonds are...

In this video Paul Andersen explains how redox reactions are driven by the movement of electrons from the substance that is oxidized to the substance that is reduced. Oxidation is the loss of electrons and reduction is the gaining of...

In this video Paul Andersen explains how an overall chemical reaction is made up of several elementary steps. The stoichiometry of this equation can be predicted but the rate law must be measured. If the elementary steps of the...

In this video Paul Andersen explains how reaction intermediates are created in elementary steps and may not appear as either a reactant or product. Experimentation is used in Chemistry to identify reaction intermediates.

Calculation of pH with known species concentration and pKa

This constant represented by the Greek letter alpha is just a dimensionless number, so no matter what units you use, it will always have the same value, about 1/137. If it was different by just 4%, life may not...

A portion of our culture distrusts the scientific method, assuming that there are transcendent truths unknowable by science. But nothing is truly out of bounds for science. If it's real, it can be studied, and tested. Perhaps the...

Ever wondered how math helps grow beautiful gardens and thriving lawns?🌻 Join us on a behind-the-scenes journey with Scotts Miracle-Gro scientists as they reveal the essential role of math in creating the products that keep...

The video is a lecture presentation on the process of making salts through experiments. The presenter demonstrates different bases, copper carbonate and copper oxide, and hydrochloric acid. The presenter explains the theory behind the...

This video explains what corrosion is and how it occurs in metals when they come into contact with oxygen and water. The video also discusses the different methods used to prevent corrosion, including barrier coatings and sacrificial...

The video discusses the reactions of acids and bases and how to name the salts that are formed during these reactions. The speaker outlines the various reactions that occur when acids react with metals, metal hydroxides, metal oxides and...
