dominant in Thin layer chromatography, particles or molecules that are non-polar travel faster at the stationary phase and the molecules that are polar spend more time at the stationary phase and therefore this means that molecules that are non-polar travel larger distance on the TLC plate in comparison to molecules that are polar since the polar molecules stick to the polar stationary phase (gel silica plate). According to Mary (1996) the molecules or substances move or travel up the…

N.p., n.d. Web. 17 Sept. 2017. This .gov article defines capillary action or the movement of water through porous material due to cohesion, adhesion, and surface tension forces. Water molecules can soak paper towels because of their sticky tendency and gravitational resistance. “Cellulose.” Gale: Research in Context. N.p., n.d.

rigidity to membranes. Summarized the manner in which small molecules are…

temperature affect gas molecules, how does kinetic energy affect temperature change, and what is the Ideal Gas Law? Matter comes in four different forms, called states: solids, liquids, gases, and plasmas. In this particular experiment the form I will be using is gas. Gas takes the shape of the container that it is inside of. It expands as the balloon is filled up and evenly distributes gas molecules inside. The gas molecules are not connected,…

How individual molecules are separated or a mixture of molecules are separated can be dependant of their size. Size exclusion chromatography (SEC), is the controlled separation technique that is based on the size of the particles in relation to the pore size (Barth and Saunders 2012). The separation process veers to be quick for large molecules and slower for smaller molecules. The process would involve the large macromolecules to permit through the column bed, as the smaller molecules…

out a way to create this elusive molecule. Triangulene is a flat molecule made of six carbon rings structured in the shape of a triangle. The problem with synthesizing this molecule is that it contains unpaired electrons in two of its outer carbons. These free electrons cause the molecule to oxidize almost instantly as these electrons react to try to find stability. The researcher team form IBM has found a way to overcome this obstacle. By starting with the molecule dihydrotriangulene,…

chemical properties, and scientists have developed intricate techniques to observe, quantify, and isolate molecules based on their aforementioned properties. Agarose gel electrophoresis, the most widely used technique in separating strands of DNA, is used to visualize and isolate strands of nucleic acids based primarily on length. The technique can be used on a mixed assortment of DNA molecules to yield information concerning the length…

oxygen molecules to the appropriate tissues that require it. Normally the oxygen that our tissues need in order to function properly on a daily basis is carried by a red protein known as hemoglobin. It is able to bind to oxygen thanks to the heme group that it has, which has a iron molecule in the center with a +2 charge. Hemoglobin is a great oxygen transporter in the sense that it has no organelles, particularly mitochondria. So that it would not be able to utilize the oxygen molecules, that…

gas. Sound travels in longitudinal waves. There is also a vibration that starts on an object, and this causes a vibration on all the molecules. When these molecules vibrate, they cause all of the other surrounding molecules to vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2. Can sound move through outer space? There is matter in…

cases also to purify certain DNA molecules that can be cut out of the gel after the electrophoresis. DNA molecules are negatively charged, and by loading them into an agarose gel and applying a current creating a uniform electrical field, these molecules will move across the gel. How far they travel, depends on their electrophoretic mobility. Size, structure and total charge have an impact on how far a molecule will migrate. By comparing the distance the molecules have migrated to a ladder, it…
