Every football team that plays in competition always has substitute players. That’s an extra number of players who can be quickly called in to replace another player if he gets hurt. The world of chemistry also has substitutes. It happens in types of reactions called single displacement reactions. This is a reaction where an element …
The reactions taking place around us and in the lab can be classified into many types. One of these is a decomposition reaction—a reaction where a compound is split into simpler substances. The reaction has a single reactant as a starting substance. This breaks down into two or more products. The general form of a …
(a) neutrons (b) electrons (c) protons (d) neutrons and protons (e) protons, neutrons, and electrons. The Correct answer is (c) Protons Explanation Atoms of the same element have the same number of protons in their nucleus. Let’s break it down… The number of protons in an atom is also called its atomic number. Now, atomic …
As humans, we are often mesmerized by the large size of our universe. The imagination runs wild when we try to think of how huge outer space and the stars are. However, there is another world that is just as fascinating. It’s a very tiny world and it all starts with the atom and its …
Every self-respecting chemist knows one thing about chemical reactions: the total mass of materials before the reaction and the mass of material after the reactions always stay the same. It doesn’t matter how different the form of matter looks after the reaction; this fact will always hold. This phenomenon is known as the law of …
In the chemistry world, we classify many things such as elements and compounds. We also classify the reactions that these substances take part in. Double replacement reactions are just one type of reaction you can get with them. In a double replacement reaction, the reaction proceeds according to this general form: AB + CD→ AD …
If you’re like most people, you probably think of things like cancer and horrible mutations when you hear the term gamma rays. You may even think of superheroes such as the Hulk that got their powers from exposure to gamma rays. Gamma rays have got a bad reputation mostly from how they are presented in …
There’s nothing better than a hot cup of chocolate on a cold day to warm the body up. If you want to make a quick cup of hot chocolate, you’ll probably start out by mixing a spoonful of your favorite hot chocolate powder into hot water. Before you add anything else to it, take some …
You’re probably familiar with a variety of mixtures such as suspensions and solutions. Colloid mixtures are one of the primary types of mixtures. They are also a common part of our everyday lives. They consist of very small particles that are dispersed evenly within a medium. These particles are larger than molecules but are still …
In many synthetic chemical processes, reality often doesn’t line up with theory. Real-world chemical reactions tend to throw up results that differ somewhat from what our nicely written chemical reactions expect. For example, impurities get in the way to mess up things. Or the reaction may not run to completion. This leaves stuff behind that …
