The lab “Aluminum Atoms” was designed to determine whether heavy-duty or house hold aluminum foil was the thicker than the other and to show the different atomic calculations of each type of foil. It was learned that heavy-duty foil is thicker than the household aluminum foil. An atom is the basic unit of a chemical element. Avogardo’s number‚ 6.02 x 1023‚ is the number of particles found in one mole of a substance. The molar mass is the weight of one mole (or 6.02 x 1023 molecules) of any chemical

Zinc and Hydrochloric-Acid Written By Kahlil Zione Date:02/02/05 Abstract: We observed the reaction between zinc and hydrochloric acid and recorded it in a table and learned wether the percentage of zinc is effected by the amounts of both substances added to the solution. Introduction The purpose of this experiment is to determine if the amount of zinc and hydrochloric acid will effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric

elements are metals. Of the metals‚ aluminum is the most abundant in the earth’s crust. Aluminum is concentrated in the outer 10 miles (16 km) of the Earth’s crust‚ of which it constitutes about 8% by weight; it is exceeded in amount only by oxygen and silicon.1 This metal can be found in group 13 (formerly group IIIA) in the periodic table‚ known as the boron group elements. It is represented by the chemical symbol Al‚ and has an atomic number of 13. Aluminum‚ also spelt Aluminium‚ comes from

Thickness of Aluminum Foil August 21‚ 2014 Purpose: To determine the thickness of aluminum foil through the use of the density formula applied to gathered data. Theory: The thickness of aluminum foil cannot be directly measured. In order to find the thickness‚ many pieces of data must be obtained and used in the density formula. The data that must be obtained is the length‚ width‚ and mass of the aluminum foil. These need to be collected because they will complete the formula: Density = mass /

CIVE 3202 A6E – Mechanics of Solids II (Winter 2013) Experiment 2: Bending of an aluminum I-beam Introduction “Beams are long straight members that are subjected to loads perpendicular to their longitudinal axis and are classified according to the way they are supported”[1]. When a beam is subjected to an external load there are unseen internal forces within the beam that one must be aware of when implementing it into any design or structure. These internal

Metals and alloys for nuclear energy There are two important ways in the making of nuclear energy: nuclear fission and nuclear fusion. Fusion and fission have a different working mechanisms‚ thus other materials are used. In a nuclear reactor fuel rods are bombarded with neutrons causing fission of the fuel. This way energy is released. With this energy water is heated to steam and with the use of heat exchangers and steam turbines electricity is generated. As fuel is usually uranium used‚ but also

Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more
