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...

This video is a tutorial on balancing chemical equations. The presenter discusses the law of conservation of mass and the importance of balancing equations to determine the ratios of reactants and products. They explain the meaning of...

Upon viewing the Investigating Chemical Reactions video series, students will be able to do the following: Define a chemical reaction as a process in which substances undergo changes to produce new materials with different properties....

This video provides an introduction to alkanes and alkenes, which are hydrocarbons that contain different types of carbon-carbon bonds. The video explains the general formula for these compounds and how to name them based on the number...

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...

Chain and positional isomerism are types of structural isomerism in organic chemistry, where compounds have the same molecular formula but different structures. In chain isomerism, the carbon backbone differs in branching; for example,...

Plastics are a miracle of modern science and are now fundamental to our everyday lives. Of course, they are also a constant reminder of our throw-away society. With support from the National Science Foundation (NSF), chemist Marc...

Despite the diverse appearance and characteristics of organisms on Earth, the chemicals that make up living things are remarkably similar, often identical. In this episode of Crash Course Biology, we’ll look at the building blocks of the...

In this video from our Chemical Calculation Series learn how to calculate Percentage Mass within a Chemical Formula.

This video provides a description of the properties and characteristics of water. It explains that water can exist as a solid (ice), liquid, or gas (steam), and is the only naturally occurring compound that can do so. The video also...

This program covers the very important topic of ionic compounds. We discuss how ionic compounds form and how to predict ahead of time what the chemical formula will be when given the atoms that form the ionic compound. We spend a great...

This lesson will reveal the rules for writing the names and chemical formulae of ionic compounds, by balancing charges and using the cross method.<br/>
Definitions included: ionic compound, binary ionic compound, oxidation state
