Josie Pierre‚ Jade Etienne‚ Jennifer DaRosa Honors Chemistry Period 1 Group 8 Mrs. Chan Topic: Chemical Explosions Due Date: 9/30/16 For this experiment‚ a few scientists are researching the changes in gas pressure and launch velocity needed to send a film canister across the room using the ignition of ethanol. The independent variable would be the different types of flammable sprays. The dependent variable would be how far the explosions are sent across the room. The constant would be way

Hess’s Law Mengyuan Wu (Millie) 7 January‚ 14 Aim: The purpose of this experiment is to determine the enthalpy change for the reaction: Introduction: It is impossible to measure the enthalpy change for this reaction directly because the process cannot be controlled. However‚ you can calculate this enthalpy change by using the Hess’s Law. Pre- lab Calculations: Calculation 1: Required Masses for Reaction The ratio of and is required to be 1:100 for Table 1: Calculation

Because the work is directly proportional to the displacement given a constant force while power is indirectly proportional to work. Therefore we can conclude that power is also directly proportional

A) January 18‚ 2011B) Empirical Formula C) The purpose is to determine the empirical formula of a metallic oxide. D) Pre Lab Questions: After heating the metal‚ the crucible and contents should mass less than it did before it was heated. This is because heating the crucible may rid of other residue that was left in it; bringing it a to a constant mass. A yellow flame will deposit soot on the crucible. This would be a problem because the soot left on the crucible would vary from our constant

A velocity vs. time graph can be used to describe both acceleration and displacement. Acceleration is shown by the slope of the graph‚ displacement by

A Chromosome Study Lab An examination of the chromosomes of a cell under high magnification can give much information about an organism. Figure 1 shows the chromosomes of a somatic cell as they might appear in an organism if enlarged many times their natural size. A somatic cell is any cell making up the organism except for reproductive cells. In this investigation‚ it is expected that you: a. learn what a chromosome Karyotype is. b. prepare a Karyotype of chromosomes according to the instructions
