calculate total magnification on a compound light microscope? How is the calculation of magnification different on the pocket microscope? The total magnification in a light microscope is the product of the ocular and objective lenses. Suppose Ocular is of 10x Objective lens is of 40 x. Total magnification will be 10X40=400. For pocket Microscope M= (LENGHT OF MICROSCOPE TUBE)/(focal length OF EYE PIECE)*(focal length of objective lens) 2. What parts of a compound light microscope can be used to control

International Union of Pure and Applied Chemistry (IUPAC) system: inorganic nomenclature organic nomenclature Organic compounds contain carbon‚ usually in combination with hydrogen‚ oxygen‚ nitrogen‚ and/or sulfur. All other substances are inorganic compounds‚ divided into three basic categories: ionic compounds molecular compounds acids Naming inorganic compounds begins with naming ions. Cations formed from metal atoms have the same name as the metal. See a chart of common cations

This type of reaction provides an alternative approach for the formation of C–C‚ C–B‚ and C–Si bonds. Moreover‚ by using tosylhydrazones as diazo compound precursors and boronic acids/esters as the boron

To: Aron Huckaba From: Peyton Lewis Date: 9/20/12 Subject: Experiment 3: “Identifying a Constituent of Panacetin” Partner: Julie Covington Introduction This experiment was a continuation of Experiment two‚ with a slightly different question to be answered. In this experiment‚ we are trying to find the identitiy of the unknown component of Panacetin. This is answering question 2 of the two questions that were to be answered in experiment 2. The equation of this reaction is as follows (and

substances: an element and a compound. Element: A substance that cannot be broken down by chemical means. An element is a pure substance because it is made up of one type of atom it also cannot be broken down further into another substance. (This deems it pure) Compound: A substance that is made up of 2 or more elements‚ it is still considered a pure substance because while the elements bond so do the atoms. Therefore there is only one type of atom in the compound. Impure substance- Mixture:

Write a paragraph that describes how each compound is attracted to each element and silica. The first eluent (A)‚ 9-fluorenone greatest IMFs are dipole-dipoles‚ although silica allows for short dipole-dipole interactions‚ which is possible because of its polar regions. This relationship is exemplified by 9-fluorenone?s high Rf values‚ and a strong affinity towards the stationary.

THEORY: - iGEMDOCK - A Graphical Environment for Recognizing Pharmacological Interactions and Virtual Screening Pharmacological interactions are useful for identifying lead compounds and understanding ligand binding mechanisms for a therapeutic target. Currently‚ these interactions are often inferred from a set of active compounds that were acquired experimentally. Moreover‚ most docking programs loosely coupled the stages of structure-based virtual screening (VS) from preparations through to post-screening

Biochemistry: categories of organic compounds Ruddy Severino There are four major compounds that compose the human body. It is impossible that anything living on earth today can live out these organic compounds. Those compounds are carbohydrates‚ lipids‚ proteins‚ and nucleotides. Each compound has a major important function that is essential to the human body as well as other living organisms on earth. Carbohydrates serve as the main source of energy. Carbohydrates contain carbon‚ hydrogen

Chromatography allows for the separation of chemical mixtures‚ generally in either a gaseous or liquid state‚ by letting the substance slowly spread past another substance‚ which is typically in either a liquid or solid state. When chromatography is performed‚ there is a stationary phase

Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of that phenomenon‚ those compounds are used to reduce moisture in places where water moisture can damage certain products. The anhydrous compounds are separated into three categories: hygroscopic
