Most Famous Oxidation and Reduction Reactions Explained with 20+ Examples
Last Updated on May 25, 2023 by Sara Assem Chemistry is the branch of science where interactions and reactions between elements, atoms, electrons, molecules, and many other particles, is mainly considered and studied. One of the most famous reactions widely abundant and occurring in chemistry, and in our day-to-day life, is the topic of this article: the process of oxidation and reduction and their reactions. Here, we will discuss the nature of these reactions, their definitions, the difference between oxidation potential and reduction potential, and the difference between oxidizing agents and reducing agents, in addition to giving oxidation vs. reduction examples to clearly comprehend the process… Let’s start! Oxidation and Its Historical Definition In case you are a fan of oxygen-based cleansers, or you are thankful for the sterilizing power of hydrogen peroxide products, then you must thank “oxidation.” On the other hand, you can blame oxidation, if you ever have dealt with a rusty car or a toss out browned fruit. Oxidation is a process that can start spontaneously or artificially; it is helpful at times and very destructive at others. The very classical example of oxidation is when iron interacts and combines with oxygen to form the …

PraxiLabs New 20+ Experiments and Updates Now Revealed!
Last Updated on June 20, 2022 by Mostafa “Not only new experiments and updates, but also discount codes!” This is how PraxiLabs latest free webinar started. On March 27, 2022, PraxiLabs held a webinar where both our 20+ newly added experiments and system updates were discussed. Our hosts, Dr. Khadija El-Bedweihy, Dr. Mona Magdy Saber, and Dr. Heba Elwi, all walked the webinar attendees through some of PraxiLabs virtual experiments and conducted two experiments live, allowing them to live the lab experience themselves. Exclusively blessed with many new features, PraxiLabs offers its students and professors: Enrichment Documents Informational content that is not necessarily scientific, rather, it discusses fun facts or historic information about the experiment. Exercises Non-repeated MCQ questions, to assess students’ understanding of the experiment. Questions can have more than 1 right answer. Safety Precautions and Infection Control Students are introduced to the lab’s safety procedures. While safety and infection control notes pop-up along the experiment. Progress Bar To help students track their progress and know whether they are moving forward with ease, or struggling throughout the experiment. Superior Time Management If it takes a specific step—say, one hour—to be conducted in the real physical lab, it takes …

Discover the World of Balanced and Unbalanced Forces with 20+ Examples and Q&A
Last Updated on February 25, 2025 by Zinab Hasssan “Force” is one of the very essential terms used in physics. Every time and everywhere we—as scientists, or as a public crowd—are about to observe or examine a phenomenon closely, we find that a force is controlling or resulting in that phenomenon. Forces are instinctively different from each other; they have many forms, and their presence is significant in almost everything in our everyday life. One of the physics bright stars of all time is the set of Newton’s laws of motion, consisting of his three very well-known laws; all of these laws discuss forces and how they interact and react, but do you know what are the many types of forces that exist and are known by scientists? Forces exist in two forms, either as a result of contact interactions, i.e., normal, tensional, frictional, and applied forces; or as a result of actions-at-a-distance interactions, existing in the form of electrical, gravitational, and magnetic forces. In general, forces are the reason causing objects to stay still, to move at a fixed rate, or to accelerate, whether by speeding up or slowing down. How many times have you tried to pull …

Your Guide to Newton’s Third Law of Motion: Detailed Explanation with 7 Examples
Last Updated on April 11, 2023 by Sara Assem The laws of physics are prominent in our everyday life, as they permeate, govern, and fully control every step we take and every move we make. The various applications of Newton’s third law of motion form a good example to recall in this context, especially within the boundaries of our solar system. In this article, we will elaborately discuss the nature of this law, its equation, and its importance in our daily life, in addition to mentioning some real life examples of Newton’s third law.. Let’s take a look! What Is Newton’s Third Law of Motion? In 1687, and throughout his Philosophiae Naturalis Principia Mathematica masterpiece, widely known as the Principia, Sir Isaac Newton proposed his renowned three laws of motion, commonly named after him. The laws mainly deal with the term “force,” but do you know what the types of forces are? Forces exist in two forms, either as a result of contact interactions, i.e., normal, tensional, frictional, and applied forces; or as a result of actions-at-a-distance interactions, existing in the form of electrical, electrical, and magnetic forces. In this law, Isaac Newton described any two objects that are …
