Amwoga Khalwale What Is Allyl? An allyl in organic chemistry is a substituent functional group with a general molecular formula RCH2CH=CH2. Allyl group holds three carbon atoms and five hydrogen atoms, which gets attached to any other group of atoms through –CH2 group. Allyl group consists of (-CH2-) methylene bridge and is attached with (-CH=CH2) vinyl group. … Read more
What Is A Jig? Jig is a work holding device that holds supports and locates the workpiece and guides the cutting tool for a specific operation. Often a jig is made of metal which locates and holds the workpiece in a positive manner and also guides the cutting tool such that it is in the … Read more
What Is Hard Iron? Hard iron is an iron which is not readily magnetized by induction but which retains a high percentage of the magnetism acquired. When a bar of non-magnetized iron is placed in magnetic field, the direction of magnetization of the magnetic domains tends to move towards the direction of the field. This … Read more
A beam is a very important component of construction or building. However, every steel or metal beam is not the same; rather they are distinguishable from each other in terms of grade, size, shape and even quality of metals used in its making. Some of the common forms of beams include: Universal Beams W-Beam H-beam … Read more
Molecular geometry in chemistry is the three-dimensional arrangement of atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom. Understanding the molecular structure of a compound can help determine the polarity, … Read more
The slab is typically the horizontal structural element of any building/house which is used to construct floors, ceilings and roofs. Generally, slabs are made of reinforced concrete. They can be simply supported, continuous or cantilever. Usually, the thickness of slabs is considerably less than their other dimensions. Slab can also be described as an element … Read more
What Is Chemical Change? A chemical change happens when one chemical substance is transformed into one or more different substances such as when ion becomes rust. Chemical changes occur throughout the process of chemical reactions and the resulting substances have different properties because their atoms and molecules are arranged differently. Chemists categorize chemical changes into … Read more
Variations, the small differences that exist between individuals can be described as being either discontinuous or continuous. What Is Continuous Variations? In continuous variation, there is a complete range of measurements from one extreme to the other. Human height is an example of continuous variation. It ranges from that of the shortest person to the … Read more
Transmission mode refers to the mechanism of transferring data between two devices connected over a network. There are three types of transmission modes, they include: Simplex Mode Half duplex Mode Full duplex Mode In simplex mode, communication flows in one direction (unidirectional). A device can only send the data but cannot receive it or it … Read more
Genotype and phenotype are two fundamental terms in the science of genetics used to explicate the appearance, function and behavior of an organism. The two terms are often used at the same time to describe the same organism but there is a big difference between. The phenotype is the result of genetic factors, environmental influences … Read more
