Determination of Manganese in Steel Submitted by: ------------------- Date of Submission: 27.03.11 Objectives: In steel production aside the iron‚ which is the primary source‚ some amounts of manganese is used together with carbon. The objective of this experiment is determining the manganese amount in the steel compound by using UNICAM UV-VIS Spectrometer. Theory: Many molecules absorb ultraviolet or visible light. The absorbance of a solution increases

the substance. Oxidation: Also known commonly as rusting‚ this process combines oxygen molecules with the mineral ions such as iron‚ calcium or magnesium. Oxygen is normally taken from the moisture in soil or air. Subsequently‚ it results in reduction of the mineral to a less stable compound. A typical example is conversion of iron (Fe) radicals into rust or iron oxide (Fe2O3) which is weaker. Reference:

side BC of triangle ABC. W is a circle which is tangent to AB and BM at T and K and is tangent to circumcircle of AM C at P . Prove that if T K||AM ‚ circumcircles of AP T and KP C are tangent together. 3. Let ABC an isosceles triangle and BC > AB = AC. D‚ M are respectively midpoints of BC‚ AB. X is a point such that BX ⊥ AC and XD||AB. BX and AD meet at H. If P is intersection point of DX and circumcircle of AHX (other than X)‚ prove that tangent from A to circumcircle of triangle AM P is parallel

from. Bangladesh has a lot of floodplains and it is very hot. For my house roof the first layer on the frame would be 15mm of triplex nailed on to the frame of the house. The design will have corrugated galvanised iron on the frame. If the water went through the corrugated galvanised iron‚ it is able to slide the water down outside. There will be big pipes on the end bottom of the roof bringing the water beside the house and using it to take showers and etc. As the floor of the attic‚ I will put a

Sensorial Education Introduction to Sensorial What is Sensorial Education? Sensorial education can simply be defined as the training of senses of children for future learning. What is Sensorial Work Sensorial comes from the words sense or senses. It helps the child to be able to concentrate on the refinement of all his senses‚ from visual to stereognostic. The Purpose of Sensorial Work The purpose and aim of Sensorial work is for the child to acquire clear‚ conscious‚ information and

Blast Furnace Hot Metal is one of the most critical problems in today’s Iron Making. With deterioration in quality of iron ore day by day‚ silica load in the burden material has a steady increase. The same story is with the Coke ash‚ which passes good amount of silicon in the hot metal. Every 0.1% reduction in silicon in the hot metal gives rise to 1.5 % increase in hot metal production. In the competitive scenario of today’s Iron Making hence it is necessary to reduce every bit of Silicon in hot metal

Manganese would be a solid. It would be classified as a metal. The color would be silver/grey. When armies were at war their helmet was made out of steel and 12% Manganese. In 1942 nickels were made out of 9% Manganese. Manganese can rust in water like iron. Manganese is also an important part of our body. Manganese can help our bodies in many ways and ruin our bodies to. Scientist shows that without Manganese we wouldn’t be able to heal from surgery faster‚ helps from bone loss‚ and is an antioxidant

Hypothesis: I think that the chemical change is an irreversible process. The wet iron filings by the next day it will turn into rusting material because it is exposed to the atmosphere. While the dry iron filings is not III Materials: The setup in the previous activity‚ small plate‚ dry iron filings. IV Procedure: 1. Place the iron filings on a dry plate. 2. Compare the physical properties of the dry and wet iron filings. 3. Take note of the differences in their physical properties if any.
