Kevin Nam Honors Chemistry 3/22/14 Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature

Title : Properties of hydrocarbon Objective : 1) To study the properties of hydrocarbons. 2) To determine the unknown samples. Results : Part A : Combustion Compounds Observations Hexane There was orange flame and burned mildly during the burning process. No soots and smoke were produced. C6H14 + 19/2 O2 6CO2 + 7H2O Cyclohexene Orange flame burned vigorously. A small amount of black soot and smoke were produced during the burning process.

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to

Honors Chemistry Period 2 September 22‚ 2013 PRE-LAB Title: Density of Metals – Shot Lab Purpose: The purpose of this lab is to find out the density of different metals using their mass and volume. If the volume and mass for the metals Nickel and Copper are found‚ then we can figure out the density. Materials: Metal shot Plastic rinse bin Electric Balances Calculator Graduated Cylinders Water Wire Gauze Weigh Boats Pre-lab Questions: 1) The volume of the water is 43.0 mL

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

Lab for Chemistry 221 Lab: How much sugar is in a Can of Coke? Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke. Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration
