1. A class that I believe was most particularly significant to me is AP Chemistry. Prior to enrolling in the class‚ I was mostly breezing through school without having to put in a considerable amount of time for homework and studying purposes. A few weeks into the course however‚ I had realized that this class was not going to be even close to the ones I have taken before in terms of the rigor and depth of understanding required to succeed. Now that I have finished the course‚ albeit with a B first

and hands-on experience that the AP Chemistry students will need. In order to create a professional laboratory atmosphere similar to industrial labs these students may work in‚ all the glassware‚ safety materials‚ and provided chemicals will be surrounding the students. The kidney tables are used for groups of three students. These groups will be used for several assessments‚ lab exercises‚ class discussions‚ and presentations. Each group will have their own lab table in the back of the room. The

Marisol Camacho AP Chemistry Per. 1-2 10/31/12 Titration Lab Titrations are a very useful method of discovering the amount or concentration of unknown substances. The method is very well suited towards acid-base reactions. Titrations are often used in industry to analyze products to be sold. In this lab‚ standardizations will be done in the first two experiments and then titration analysis in the third. Standardization of a base (NaOH) using a primary standard (KHP) Standardization

Chemistry 121 Colligative Properties Lab Demonstration of Selected Calculations from Choice I Determination of Kf for Naphthalene To determine the Kf for naphthalene‚ we need to find the difference in the freezing point of pure naphthalene and the solution of 1‚4-dichlorobenzene in naphthalene. Let’s say that we did this experiment‚ used 1.00 g 1‚4-dichlorobenzene in 10.00 g naphthalene‚ and found that the freezing temperature of pure naphthalene was 78.2°C‚ while that of the solution was 75

A reaction may release or absorb energy‚ and a phase change may do the same‚ such as in melting and boiling. Thermochemistry focuses on these energy changes‚ particularly on the system ’s energy exchange with its surroundings. Thermochemistry is useful in predicting reactant and product quantities throughout the

Thermochemistry Photo by: Arto Thermochemistry is the study of the heat released or absorbed as a result of chemical reactions. It is a branch of thermodynamics and is utilized by a wide range of scientists and engineers. For example‚ biochemists use thermochemistry to understand bioenergetics‚ whereas chemical engineers apply thermochemistry to design manufacturing plants. Chemical reactions involve the conversion of a set of substances collectively referred to as "reactants"

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements
