There are different types of Compound Interest. Interest is the amount of money earned in a saving account. * Simple Interest: Interest calculated once on the principal. * Compound Interest: Interest calculated for a given segment of time of the investment. For example‚ compounded monthly‚ means the interest is calculated each month and combined with the principal. So‚ for the next month‚ interest is earned on the interest.

A metal is defined as an opaque shiny element which possesses properties such as malleability and ductility. Malleable meaning that they can be hammered into shapes and ductile meaning they can be drawn into wires. They are also very strong and posses high tensile strength and are good conductors of heat and electricity. Metals are shiny‚ and also have high densities. Metals are a very important and significant part of chemistry. However‚ their importance is not just limited to chemistry; they are

Lab 6: Organic Compound Analysis Isabella O’Toole CHY 116 Friday 1:15-4:00 Lab Conducted on 4-12-13 and 4-19-13 4-26-13 This lab was conducted in order to determine the chemical composition of an unknown organic acid. A known mass of acid was dissolved into 30mL of either water or methanol (depending on solubility) and titrated with standardized sodium hydroxide. Data from this allowed the molar

Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is also to

Discussion The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order

After conducting the test they concluded their investigation by stating the crashed was cause my metal fatigue. After many repeated cycle of pressurization and de-pressurization of the aircraft cabin the cabin began to worn down and break apart.
