Title: Compound Pendulum Background: Background 1 by Syahnaz Azlin Razlan The experiment “Compound Pendulum” was conducted on 13th August 2008 in Machines Dynamics Laboratory. The experiment was conducted in groups of four‚ and was supervised by lecturer Mr. Mohd Azahari Johan. Conducting this experiment is for fulfilling the requirements of Applied Mechanics Lab (MEC 424). A pendulum is defined as body so suspended from a fixed point as to swing freely to and from by the alternate action

isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for subsequent reaction. This "photo equivalence law" was derived by Albert Einstein during his development

Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent Bond Bond

*Compound Interest/Discount* Compound Interest When you borrow money from a bank‚ you pay interest. Interest is really a fee charged for borrowing the money‚ it is a percentage charged on the principle amount for a period of a year - usually. If you want to know how much interest you will earn on your investment or if you want to know how much you will pay above the cost of the principal amount on a loan or mortgage‚ you will need to understand how compound interest works. * Compound interest

complex metal ion? A complex is a molecule or ion formed by the reaction of two or more ions or molecules capable of independent existence. What is COMPLEXATION????? Chemical reaction that takes place between the metal ion and a molecular or ionic entity (known as ligand). Also known as Chilometric titration‚ Chilometry‚ Chilatometric‚ EDTA titrations. It is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration.

different types of Sodium chloride‚ coarse and fine‚ they still had a symmetrical‚ three-dimensional shape. All ionic compounds have this structure. It was also found that Sodium chloride had a high melting point and sugar had a low melting point. This is because Sodium chloride is ionic and the bonds holding it together take much more energy to break. Sugar‚ on the other hand‚ is covalent so it took less energy because the bonds aren’t as strong. This was found through heating the two substances over

Purpose The goal of the investigation was to observe if certain solutes would result in dissolving in different solvents. Solubility is what determines if a substance will dissolve in a certain solvent. The ionic solutes will dissolve into the polar solvents and the covalent solutes will dissolve into the non-polar solvents because the molecules of the solvents have a stronger force that will break apart the solute and dissolve it into the solvent. Procedure Small amount of the solutes‚ roughly

Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain by a single covalent bond are called straight
