investigated to see how the change in concentration of hydrogen peroxide and the change in temperature affect the rate of reaction. The data will be collected by measuring the gas pressure. The product of Hydrogen Peroxide is oxygen in a gas state thus it is mandatory to use the gas pressure sensor. By calculating the difference of the gas pressure divided by the amount of time from the raw data collection it is able to find the rate of reaction of the decomposition of hydrogen peroxide. * Control Variable-

city‚ heard a commotion outside his window early in the morning at about 3 a m. It was a chill December and all the windows of Chitre’s house were closed. As Chitre and his wife Rohini‚ seven months pregnant‚ opened the window‚ they got a whiff of gas. They immediately felt breathless and their eyes and noses began to stream with a yellow fluid. Sensing danger‚ the couple grabbed a bedsheet and ran out of the house. Unknown to them‚ all the neighbouring bungalows‚ which had telephones‚ had already

Unit 6 Problem Set 1: Applying Thermal Expansion Learning Objectives and Outcomes Calculate the thermal expansions of solids and liquids. Assignment Requirements Complete the following problem. Show all of you work. The formula for the linear expansion of a solid is given by: An iron rod (α = 11.8 x 10-6 C-1) has a length of 1000 meters (or 1 km) at 0 degrees Celsius. If the rod must expand 10 cm to bridge a gap‚ to what temperature must the rod be heated? Increase in L = a*(T-To)L

Cola Explosion When the Mentos come into contact with the Diet Coke‚ a reaction causes the rapid formation of foam. it is concluded that the potassium benzoate‚ aspartame‚ and CO2 gas contained in the Diet Coke‚ in combination with the gelatin and gum arabic ingredients of the Mentos‚ all contribute to the formation of the foam. The structure of the Mentos is the most significant cause of the eruption due to nucleation.MythBusters reported that when fruit-flavored Mentos with a smooth waxy coating

that is poisonous to cells. Catalase speeds up the decomposition of hydrogen peroxide into harmless water and oxygen gas. The purpose of this lab was to determine whether an inhibitor affects the rate of activity for the enzyme catalase. Since catalase speeds up the production of oxygen gas‚ the rate of enzyme activity can be measured as the height of the column of oxygen gas bubbles produced in a test tube. If copper sulfate inhibits the action of catalase‚ then it will slow down the reaction

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

for a Closed System Question A gas is contained in a cylinder fitted with a movable piston as presented in Figure E6.4.1. Figure E6.4.1: A cylinder fitted to a moving piston If the cylinder is placed in boiling water with the piston held in a fixed position‚ 5 kcal of heat is absorbed by the gas‚ which equilibrates at 150oC and a higher pressure. The piston is then released‚ and the gas does 250 J of work in moving to its new equilibrium position. The final gas temperature is 150oC. Write the
