Covalent Compounds – Polar and Nonpolar

We know that covalent compounds are the compounds formed by the sharing of electrons. Lets see what are the different conditions required for the formation of covalent compounds. The first condition is that both the atoms should have a high ionization enthalpy. Ionization potential or ionization enthalpy is the energy required to remove an electron […]

TRU Chemistry Lab: First Year Experiment – Acid (ASA) Synthesis – Purity Tests

Purity tests. This week you will be introduced to thin layer chromatography TLC and melting point determination. The first purity test we will be doing is TLC Which, stands for Thin Layer Chromatography It works on the principle that it works on a stationary phase and a mobile phase to separate a mixture. It separates […]

Classification of Acids | Chemistry

Hello students, we’ve already learned about acids in our previous lessons. In this lesson, we shall see how acids are classified. We know that acids are substances which are sour to taste and you also know that acids are called acids because they produce H+ ions in water. Now, depending upon these H+ ions, we […]

Precision-Livestock-Farming and Animal Nutrition | Evonik

Digitalization in farming is something that has been going on now for probably over 20 or 30 years It’s really becoming much more focus now on collecting information and allowing advisors and farmers themselves to analyze all of this information and make good science-based decisions on the information that they have Evoniks approach to precision […]

Polar Molecules Tutorial: How to determine polarity in a molecule

in which we will explore how bond polarity affects the polarity of a molecule so what is polarity? First molecules are neutral; the entire molecule has an equal amount of protons and electrons; with that in mind if the negative charge, the electrons in a molecule, are evenly distributed around the molecule, then it is […]

Vitamin B12 or Cobalamin: Chemistry in its Element podcast

The Chemistry in its Element podcast Curious tales of chemical compounds It’s January, a new year and a new start, maybe even a new you? Perhaps you’ve started going to the gym, you’ve picked up the musical instrument that you’ve lost the knack for or resolved to bake more often. And like that discount trial […]

Chemistry: What is a Covalent Bond? (Polar and Nonpolar)

The bonds that hold atoms together in compounds are called intramolecular forces. The 3 main types of intramolecular forces are ionic bonds, covalent bonds, and metallic bonds. This video will focus on covalent bonds: Ionic bonds and Metallic bonds will be featured in their own videos. Covalent bonds are stable because the bonding atoms achieve […]
