Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate

Grass Decomposition Lab Problem: How do temperature‚ sunlight‚ amount of moisture‚ and presence of oxygen affect the decomposition of grass? Controlled Variable: Amount of grass and water in each container. Independent Variable: temperature‚ sunlight‚ amount of moisture‚ presence of oxygen. Dependent Variable: decomposition rate of grass. Hypothesis: I believe that there will be the most decomposition in high temperatures‚ low sunlight‚ low amount of moisture‚ and high presense

The Decomposition of Baking Soda Purpose: - To determine the correct balanced equation for the decomposition of baking soda using % yield. PreLab Notes: Sodium Bicarbonate (Baking Soda) decomposes when heated yielding both gaseous products and solid products. The production of gas makes baking soda a leavening agent in baked goods. The trapped bubbles of gas give muffins and cakes a lighter‚ airier texture. When heated‚ baking soda decomposes in one of the following unbalanced equations.

Introduction The main theory of the experiment is that an object needs an amount of heat for it to change a unit mass by 1 degree in temperature. The objectives of the experiment are to determine the specific heat of metal specimens using the method of mixture‚ to measure the equipment properly‚ to carefully measure the temperature of the equipment‚ to be patient while waiting for the output of the experiment and to be precise in computing for the specific heat of the specimen.

Capacity for a Calorimeter and of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The enthalpy of reaction for an acid-base reaction

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2

Thermal hydraulics analysis of supercritical water reactor core design Jianguo Zhong‚ Michael Podowski Abstract: This paper started with a literature survey of development the supercritical flow reactor core design‚ various coolant flow path designs were discussed: conventional one-pass flow arrangement‚ two-pass and the three-pass coolant flow geometry. A simple 1-D model was developed for the one-pass and two-pass flow design to find the maximum flow bulk temperature and case temperature in

The Enthalpy of Formation of Magnesium Carbonate By: Jessica Miller T.A: Thomas Lab Partner: Rebekah Melanson Thursday Lab Room 106 Chemistry 1001-A Due Date: Thursday February 3rd 2011 Abstract The purpose of this experiment was to determine the enthalpy of formation of magnesium carbonate in a lab setting. This was done using a calorimeter‚ which was calibrated by adding a known amount of both hot and cold water. Following the calibration of the calorimeter‚ HCl was placed into the empty calorimeter
