Overview
Heavy oil: the steamy bandit
Chemistry
Energy
Petroleum
With a natural viscosity ranging from molasses to tar, the world’s vast resources of heavy crude (SN: 7/21/79, p. 42) require heating–generally with steam–before they can be coaxes dout of underground reservoirs. Now engineers at Sandia National Laboratories in Albuquerque have identified an energy-robbing phenomenon that’s costing heavy oil producers dearly: It’s called wellbore refluxing….
Thin-Layer Chromatographic Analysis of Drug Component
Chemistry
Scientific method
Techniques
TLC is used because it is “sensitive, fast, simple and inexpensive analytical technique”2 (Mohrig 151). The unknown solid (unknown #3 in this case) used in the experiment was obtained and added to a 2. 5ml of Ethanol/dichloromethane in a test tube. This was the solvent used in the experiment because Dichloromethane volatility and ability to…
Types of Chemical Weathering Sample
Chemistry
Chemical Weathering is the procedure of decomposition or decomposition of stones due to chemical procedures. It alters the intrinsic belongingss such as chemical construction. composing and denseness of the minerals that the stone is made up of. A rock’s susceptibleness to Chemical Weathering depends on the stableness of the minerals in it. Rock is composed…
X-Ray Interaction With Matter
Chemistry
Energy
Radiation
An X-ray (composed of photons) has a lot of intrinsic energy and when it passes through matter that comes on its path, it would interact with the matter and either by absorbed by the matter (energy gets transferred to the matter) or be redirected in other directions (scattered). Various substances depending on their inherent properties…
The Dye And Classification
Chemistry
By definition, dyes can be said to be coloured, ionizing and aromatic organic compounds which show an affinity towards the substrate to which it is being applied. It is generally applied in a solution that is aqueous. Dyes may also require a mordant to better the fastness of the dye on the material on which…
The Luminescence of Black Light
Chemistry
Light
Nature
What is it? It is a portion of the Ultra-Violet Spectrumthat is invisible to our eyes. We can not distinguish it. However, when thisradiation impinges on certain materials visible light is emitted and this isknown as “fluorescence.” Fluorescence is visible to the human eye, in that itmakes an object appear to “glow in the dark.”There…
The Solution, Solvent and Solute
Chemistry
Nature
Water
Compare and contrast solution, solvent, and solute. What properties of water make it an effective biological solvent, and how does a molecule like NaCl become dissolved in it? How is the concentration of a solution determined? What is molarity? Tell me how to make a 1 M solution of NaCl. Answer: A solution is made…
