Percent composition is the percent of total mass of one element in a compound. We can find the percent composition by using this formula: mass of element/total mass of compound times 100. In this video, we will cover what percent...

In this video, we're going to learn about the number of p, n and e in an atom. We'll explore the atomic structure of different elements, and see how the number of protons, neutrons and electrons affects the properties of those...

This video highlights the amazing capabilities of plants and the importance of photosynthesis in sustaining life on Earth. It also explains the process of human respiration, detailing the intricate structure of the lungs and the role of...

This video explores how chemical reactions create light and power various processes, from lighting up a room to propelling a rocket into space. It also delves into the fascinating ways chemical reactions occur within our bodies,...

The empirical formula tells us the lowest whole number ratio of elements in a compound. We can find the empirical formula using 4 easy steps. In this video we will cover those 4 steps and work through 2 practice problems to show you how...

In this video we walkthrough 3 limiting reactant practice problems step by step and show you how to solve them!

The molecular formula of a compounds gives you the actual formula while the empirical formula gives you a simplified version of the molecular formula. Both formulas are important in chemistry and they both gives us valuable information....

In this video, the Amazon rainforest is explored as a vital contributor to our planet's oxygen production, earning it the nickname "the lungs of the Earth." The video highlights the Amazon's diverse ecosystem, its heavy reliance on...

Researchers at London's Imperial College are using X-ray crystallography to understand how plants break down water into hydrogen and oxygen through photosynthesis. This breakthrough could lead to the production of cheap hydrogen, as they...

Atoms are the basic building blocks of all matter and they are very very small. They are made up of protons, neutrons and electrons and they are the smallest unit of matter that still retains the basic properties of an element.

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...

In acid and base chemistry, we learn that there are 3 main types of hydrolysis: salt, acid and base. In this video, I will show you a fun and crafty way to spice up your organic chemistry notes on this topic.

Monosaccharides are the simplest forms of carbohydrates. Their classification, structure and examples are going to be discussed in this video.

What is an atom? And what is it made of? In this video, I will be introducing you to the atom. We will also look at concepts like atomic mass, elements and isotopes.

In chemistry, we usually talk about atoms and molecules. When we introduce the term 'element', things get a little confusing. In this video, we will cover what an element is in chemistry and give you some examples.

When 2 monosaccharides come together and form a glycosidic bond, they become a disaccharide. In this video, we will be looking at the structure and examples of disaccharides we find in nature.

Hydrolysis is a water-based chemical reaction, where water is used to break down a specific substance or molecule. In this video, we will look at a specific type of hydrolysis - hydrolysis of carbohydrates. We will learn how water is...
