Question | Endothermic and Exothermic Reactions: Examples and a simple Explanation

Chemox: A ball and a feather are falling at exactly the same speed in a vacuum. Normally, you would be right with your assumption that the ball is faster,...

Question | What is falling faster in a vacuum: A ball or a feather?

Chemox: The chlor-alkali electrolysis is used for the production of chlorine and caustic soda in large quantities. The process is still up-to-date today,...

Question | Which Chemicals are produced in the Chlor-Alkali Electrolysis?

Square: The centrifugal force comes from the Latin words centrum = middle and fugere = flee. So, it's fleeing from the middle. The centripetal force...

Question | Centripetal Force and Centrifugal Force: What is the Difference?

Chemox: All three terms are related to electricity. Depending on what you want to measure you take one or them. Each are units in which a certain amount of...

Question | Difference between Volt, Watt and Ampere

Chemox: Defining a general rule is really a bit difficult, but it can be derived from the periodic table. The fewer electrons in the valence shell, the more...
