Breaking down all you need to know to keep your hot tub water clear. Alkalinity, PH, Calcium, Testing, Enzymes and Chlorine.
A 8 minute walkthrough on key concepts and a guide on the routine Chris follows with his own hot tub.

In this tutorial video, we determine the empirical formula of an organic compound containing carbon, hydrogen, and oxygen from combustion analysis data.

Keep your pool water balanced and close to neutral, and avoid scaling, corrosion, and cloudiness, all with just three pool chemistry components. This isn't just about pool chemicals for beginners, though. Bet you could use a refresher.

Swim University®️ has made swimming pool and hot tub care easy for more than 10 million homeowners. And each year, we continue to help more people with water chemistry, cleaning, and troubleshooting. We know taking care of a swimming pool or spa can be difficult. And it’s hard to find a trusted source of information. We get it! This is the reason we created Swim University®️.

In this tutorial video, we compare trends in the first ionization energy, second ionization energy, and third ionization energy for Na, Mg, and Si. Electron configurations are used to determine if a core electron or valance electron is being removed.

Chemists need stoichiometry to make the scale of chemistry more understandable - Hank is here to explain why and to teach us how to use it.

Learning Objective: Evaluate the number of valence electrons and core electrons from the electron configurations.

Topics: core electrons, valence electrons

In this example problem, we show how to fill a molecular orbital diagram for a diatomic molecule and use molecular bond theory to compare bond order, bond strength, and magnetic properties (paramagnetic or diamagnetic).

Use molecular orbital theory to determine:
a.) the bond order of N2
b.) whether N2 is paramagnetic or diamagnetic
c.) order of increasing bond strength for N2, N22-, N2+

Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Understanding basic chemistry concepts is important for almost every profession. Chemistry is part of everything in our lives.

In this video Chemistry 101 - Atomic Structure, we study atomic structures which refers to the structure of an atom that comprises of Nucleus, Protons, and Neutrons.

Nucleus - is the positively charged center of the atom consisting of protons and neutrons.
Protons - Positively charged subatomic particle forming part of the nucleus of an atom
Neutrons - A subatomic particle forming part of the nucleus of an atom.

Our collection of videos in Chemistry covers most of the syllabus for exams such as WAEC, NECO, JAMB, and GCE.

In this example problem, we use an element's molar mass and Avogadro's number to convert from grams of an element to atoms of an element.
