...POINT LISAS CAMPUS Esperanza Road, Brechin Castle, Couva LAB 1 Decomposition reaction Aim: Determination of the number of moles of water molecules of crystallization present in hydrated Magnesium Sulphate (MgSO4.xH2O) Apparatus: Mass balance, test tube, test tube holder, heat-proof mat and bunsen burner. Reagents: Hydrated sodium carbonate. Theory: Chemical decomposition, analysis or breakdown is the separation of a chemical compound into elements or simple compounds. A more specific type of decomposition is thermal decomposition or thermolysis, which is caused by heat. ABA+B, the reaction is endothermic, since heat is required to break the chemical bonds. Most decomposition reaction require energy either in the form of heat, light or electricity. Absorption of energy causes the breaking of the bonds present in the reacting substance which decomposes to give the product. When a hydrated salt is heated it decomposes into a pure form of the salt and water. MgSO4.xH2O MgSO4 + H2O Procedure: Refer to Handout Results: A. Mass of test tube/g = 21.77 B.

Lab Report

...This experiment will separate the components of a mixture on the basis of their differing absorptive tendencies on a stationary phase, which is the method of chromatography. The mobile phase will consist of four distinct transition metal cations dissolved in an acetone-hydrochloric acid eluent, along with three unknown solutions; the identities of these will be determined based on a comparison of the Rf value of these to the known cations. First to be prepared was the stationary phase, or chromatographic paper, which in this case was filter paper. Given only large sheets, it was cut into a rectangle with 20 cm length and 10 cm width. Before cutting, though gloves were put on so that skin oil would not stain the filter paper. Also, the filter paper was not laid on the lab table, but on a paper towel. With a pencil, a line was drawn 2 cm from the bottom edge of the paper. Marks were put on the line, 2 cm apart, and labeled with the appropriate cations and the unknowns labeled as U1, U2, and U3. The stationary phases were then spotted with the corresponding knowns and unknowns, then dried under a heat lamp. This spotting process was repeated 3 times. It was done using glass capillary tubes; these used adhesive and cohesive forces to draw up the cation solutions into the tube and subsequently released them onto the filter paper when touch. With the stationary prepared, the developing chamber was made. In a 600-ml beaker 9 ml of acetone and 1ml of 6 M HCl were combined (under...

Components of Fitness

...Components of Fitness The 6 components of physical fitness are; muscular strength, muscular endurance, flexibility, speed, body composition, aerobic endurance and the components of skill-related fitness; agility, balance, co-ordination, power and reaction time. I will relate the components of fitness to my chosen sport-netball. 6 components of physical fitness Aerobic endurance Aerobic endurance is having the ability to exercise for a long period without getting tired. During aerobic work the body is dependent on oxygen; also athletes who are good at aerobic endurance will have slow twitch fibres. This component is suited for an ectomorph because of their small body surface area, light frame and good thermo regulation, which is suitable for endurance based sports such as a triathlon. Aerobic endurance relates to netball because you have to continually run up and down the court for the duration of the netball game. Muscular endurance Muscular endurance is having the ability to keep contracting your muscles without getting tired. During an activity that uses muscular endurance they will use slow twitch fibres because of the endurance of the activity. This component is suited for an endomorph because of their large lung capacity they are able to do sports like rowing, which needs muscular endurance. They are also able to increase their muscle mass easily. In netball you need to have good muscular endurance because you use your leg muscles – triceps and hamstrings-......

Rules of Mixtures for Elastic Properties

...RULES OF MIXTURES FOR ELASTIC PROPERTIES The paper is about the rules of mixtures which are used to express the dependencies of the physical properties and mechanical properties which depend on type, form, quality and arrangement of its constituents, but they are based on various assumptions so one should with caution, especially if they are used anything more than preliminary design. The paper mainly concentrates on expressions for elastic properties which are as follows: Unidirectional Ply- longitudinal modulus: The Figure 1 clearly shows the orthogonal axes and fiber direction, the fiber directions. The first approximation made is E3= E4. And also for deriving the rules of mixtures the following assumptions are made: Fibers are uniform, parallel and continuous. Perfect bonding exists between fibers and matrix. A longitudinal load produces equal strain in fiber and matrix. Using the above assumptions and approximations two rules of mixtures are derived which are E1 = EfVf + EmVm = EfVf + Em (1- Vf) V12= vfVf+vm+Vm These two rules of mixtures are generally accepted as it goes well with experimental data. Unidirectional Ply- Transverse modulus: In this the rules of mixtures are less reliable than those for longitudinal properties as they are based on assumptions of stress distribution. In this the poisson’s contraction is ignored and the stress is assumed to be the......

Only a small fraction of the remaining freshwater is usable by humans, underscoring the importance of treating our water supplies with care. Introduction It is no secret that water is one of the most valuable resources on planet Earth. Every plant and animal requires water to survive, not only for drinking, but also for food production, shelter creation and many other necessities. Water has also played a major role in transforming the earth’s surface into the varied topography we see today. While more than 70% of our planet is covered in water, only a small percent of this water is usable freshwater. The other 99% of the water is composed primarily of salt water, with a small percentage being composed of 23 Water Quality and Contamination glaciers. Due to the high costs involved in transforming salt water into freshwater, the Earth’s population survives off the less than 1% of freshwater available. Humans obtain freshwater from either surface water or groundwater. Surface water is the water that collects on the ground as a result of precipitation. The water that does not evaporate......

Mixtures and Compounds

...Mixtures and Compounds XXXXXXXX XXXXXXX XXXXXXXX SCI-110 9 May 2011 Mixtures and Compounds Describe the difference between a mixture and a compound. Chemical compounds are in every known object or substance. They are composed of two elements that combine with each other. They can also be more than two elements. Compounds are one of three forms of matter, and the other two are element mixtures. Compounds have a definite composition, as water will always consist of 88.9% oxygen and 11.1% hydrogen. In contrast, the elements that make up a mixture of iron and sulfur are black iron granules and yellow sulfur crystals which are recognizable. By use of a magnet, iron can be removed from the mixture, and sulfur can be dissolved. In addition, iron and sulfur can be mixed together by just stirring them together (Clarified, 2011). Suppose that you have a pure substance. How can you tell whether it is a compound or an element? A pure substance is an element that cannot be broken down by chemical techniques, like heating, cooling, or reactions from chemicals. This type of pure substance has only one atom, like copper, gold or silver. A large chunk of gold will have millions of gold atoms, and no other atom exist in it. Take for example if you were to heat up copper to the point you melted it, the smallest unit of copper, called an atom is still copper, regardless if it is a solid, liquid, or gaseous state. The atom is the smallest subdivision of an element, but...

Math of Mixture

...Last printed 9/20/2007 1:40:00 PM Mixture Problem – Explanation There is a difference between percent and amount. Percent is a rate. Amount is a quantity. If I told you I drove 60 mph for 3 hours and asked how far I had driven, you would not respond 60 mph (a rate) but rather you would state the quantity180 miles. It is important that you make the distinction between rate and amount, particularly throughout the process of solving a mixture problem. When analyzing mixture problems it is essential to convert to and discuss quantities (amounts) not rates. When analyzing a mixture problem, as in many other problems, a winning strategy is to find some quantity (amount) in the problem which can be expressed in two different ways thus arriving at an equation which can be solved. Consider the following mixture problem. Problem: What quantity (amount) of a 60% acid solution must be mixed with a 30% acid solution to produce 300 mL of a 50% acid solution? Analysis: In this analysis (an integral part of the solution process) I will state the steps in logical order. Beneath each step, in small blue indented type, I will state the reason/logic/explanation for that step. (1) Let x be the amount of the 60% solution to be added. Begin by assigning a variable to the quantity (not the rate) of material you are to determine. (2) The amount of the final solution is 300 mL. The problem statement dictates that the final quantity be 300 mL. (3) The amount of acid in the final solution is...
