Dec 18, 2021

In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll wrap your head around today’s topic: galactic halo! When you look at a random galaxy, your eye is drawn to the disk. That’s not surprising, considering that the disk contains the vast majority of stars, and thereby gives off the most amount of light. But there’s a lot more to a typical galaxy than just the main disk of stars. Beyond the central disk lies something called the galacti ...read more

6 Important Tin Compounds and their Chemical Reactions

Dec 19, 2021

Tin can combine with other atoms in two ways to form several tin compounds It can covalently share the two p electrons (5p2) in the outermost shell of its atom to form tin(II) compounds. These compounds dissolve in water to give tin(II) ions, Sn2. It can also covalently share all the four electrons (5s25p2) in the outermost shell of its atom. Tin(II) compounds are strong reducing agents since they can be readily oxidized to tin(IV) compounds.  Here are 6 important tin compounds us ...read more

The Importance and Role of the Nucleus in Cell Division

Dec 19, 2021

If a fertilized egg is deprived of its nucleus it fails to develop properly; in fact the enucleated egg usually dies unless the nucleus is returned within a short period of time. This in itself shows that the nucleus plays an important part in cell division and in directing the development of the fertilized egg into an embryo. The nucleus is, of course, required for cell division, but it also determines the type of structure which the cell eventually develops into. This has been demonstrated ...read more

Isomorphism and the Characteristics of Isomorphous Compounds

Dec 19, 2021

Substances which form very closely related crystals are said to be isomorphous, but it is not always very easy to decide when two substances are isomorphous. The term, moreover, is used somewhat loosely, for it originated from a consideration simply of the external form of crystals, and it was associated, by Mitscherlich’s law of isomorphism, with chemical composition. It is now realized that the requirement for isomorphism is similarity of internal structure, and, on this basis, isomorpho ...read more

Collision Theory and Factors Affecting Rate of Reaction

Dec 20, 2021

The Collision Theory assumes that there must be collision between reactant particles for a chemical reaction to occur. Although there are many such collisions, only a small fraction of them result in a reaction; these are called effective collisions.There are several factors that affects the rate of reaction in a chemical system, however, we first examine the role of activation energy in chemical reactions In a reaction system, particles move about at different speeds as they process differe ...read more
