Your thyroid is a tiny gland in your throat, and what it lacks in size, it makes up for in power. This thing controls your metabolism, so you literally can't have power without it. And unfortunately, there's a lot that can go wrong...

The chemistry behind film photography is pretty fascinating. How do film cameras help us turn light into a physical image?

Radiation sickness been portrayed in movies and television for more than 50 years. And those portrayals vary a lot. But if there’s one thing pretty much all these portrayals have in common, it’s that they get radiation sickness wrong—at...

How do adult strawberry poison frogs pass on toxins to their tadpoles? What happens when scientists add iodine to axolotl tanks? Find out, as our How To Adult hosts Rachel Calderon-Navarro, Project Manager at DFTBA, and Hank Green face...

In the previous episode we discussed what happens when we use electrophilic aromatic substitution to add a group to a benzene ring, but what happens when you try to add even more groups? Well, things get a little more complicated. In...

Dieting and exercise can be good for you, but just because something’s healthy, that doesn't mean more is even healthier.

Howcast - Your body needs iodine for normal thyroid gland function. If you've got thyroid issues or have a restricted diet, there are many ways to get iodine into your diet.

Blisters are painful and irritating, but many can be treated at home by following these simple steps.

Iodine used on skin before surgery can be a lasting eyesore. Make the redness disappear so you can focus on recovery.

Analyzes how Le Chatelier’s Principle applies to concentration changes

Explains how comparing 𝑄 Q with 𝐾 K determines the direction of reaction shift

Explains the significance of 𝐾 𝑐 K c ​ , which relates concentrations of reactants and products at equilibrium

Discusses equilibrium in gaseous reactions and the role of partial pressures

Discusses the reversible reaction between hydrogen and iodine to form hydrogen iodide

Explains how dynamic equilibrium is a state where reactants and products interconvert at equal rates

Highlights reactions that can proceed in both forward and reverse directions, reaching a state of balance.

Molecules like PF5, SF₆ defy the octet rule, with expanded valence shells or unpaired electrons, arising from the availability of d-orbitals or radical stability

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 three chemical solutions to create an oscillating reaction. The three different solutions are mixed using a magnetic stirrer and the colour changes from clear to amber to dark blue. This pattern repeats as the concentrations of...

Halogens are hazardous to human life, yet they can also be very useful. How do they react when they meet other elements? Chemistry - Periodic Table - Learning Points. The halogens are the elements in Group 7 of the periodic table. The...

The inductive effect can also influence a molecule’s dipole moment, which measures the separation of charges within a molecule. Electron-withdrawing groups create a stronger dipole by pulling electron density away from less...
