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

We put three different plants under different conditions to demonstrate that both light and carbon dioxide are needed for photosynthesis to occur. A leaf from each plant is taken and heated in ethanol to remove the pigment. These are...

We use potassium ferricyanide and luminol indicator to show how forensic scientists detect blood at crime scenes. The luminol indicator contains luminol, sodium hydroxide and hydrogen peroxide. When luminol comes into contact with the...

We use coloured agar cubes to see how different shapes change the rate of diffusion. The cubes are made using sodium hydroxide and phenolphthalein indicator to give them a pink colour. When these are added to hydrochloric acid, the...

We use maggots to let us observe aerobic respiration. The maggots are placed over sodium hydroxide in a specimen tube. A bung and delivery tube are attached to the specimen tube that feed into a boiling tube of coloured water. In 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.

It explains the concept of Stoichiometry, Concentration of Solution, Mole Fraction, Molality & Molarity.
