Analysis of Silver in an Alloy Introduction In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are

characteristics in response to changes in temperature‚ electric fields‚ and/or magnetic fields. Usually‚ four types of materials are commonly used for actuators: * shape memory alloys‚ * piezoelectric ceramics‚ * magnetostrictive materials‚ * and electrorheological/magnetorheological fluids. Shape memory alloys are metals that‚ after having been deformed‚ revert back to their original shapes when temperature is changed. Piezoelectric ceramics expand and contract in response to an

Introduction of Lab 5: Analysis of a Zinc: Aluminum Alloy The analysis of a metal alloy was designed to learn how to use the Ideal Gas Law (formulas listed below) in a laboratory setting in relevance to acquiring moles of gas created‚ thus giving us one step closer to finding the molar mass. The importance of the Ideal Gas Law‚ as well as the other gas laws‚ is that it signifies the relationship between the properties of an ideal gas. These properties assist in the explanation of the Kinetic Molecular

fuselage. The spar carries flight loads and the weight of the wings while on the ground. Hence‚ in order to do the materials for a wing spar needs to be very strong and highly elastic. For the Boeing 737‚ the spars of the wings are made up of aluminium alloy 7178 which mainly consists of aluminium‚ zinc‚ magnesium‚ chromium & copper composites. In this section‚ we will briefly descript the aluminium 7178 properties‚ its test standard‚ reasons why this material are chosen to make this part of the wing spar

Where It All Started Today Baseball is considered America ’s national pastime. American ’s began playing baseball on informal teams in the early 1800 ’s. At this time they had only local rules that differed from place to place. Also‚ at this time there were no official baseball bats for the players to use. Many used sticks as bats. That is where stick ball came from which is still played today. Baseball was based on the English game of rounders. Alexander Joy Cartwright of New York invented
