FE 106 GENERAL CHEMISTRY EXPERIMENT-3 CHEMICAL KINETICS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will study the rate of decomposition of hydrogen peroxide to form oxygen according to the net equation: 2H2O2 (aq) 2H2O(l) + O2 by measuring the rate at which oxygen evolved‚ we will investigate how the rate changes with varying initial concentrations of hydrogen peroxide and iodide

Measure the potassium iodide. Weigh out approximately 2 g of solid KI. This amount is a large excess over that which is needed. 3. Oxidize the iodide ion with hypochlorite ion. Using a graduated cylinder‚ transfer 25 mL of the dilute bleach into an Erlenmeyer flask. Add the KI and about 25 mL of distilled water. Swirl to dissolve the KI. Working in a fume hood and slowly with swirling‚ add approximately 2 mL of 3 M HCl. The solution should be a dark

Ogilvy & Mather went on air in early April. The film starts with a mother and son racing in the woods. She is shown pitting herself against the boy in regular sprints. The mother tells the story through the voice over. She says‚ “Mere bête ko jeet ki aadat tab lagegi jab woh mujhe harayega” (My son will learn the habit of winning when he defeats me). But she is in mood to let her son win by giving in. “Akhir adatein na ek din mein banti hay na asani se” (Habits are neither built in a day nor easily)

equals the change in kinetic energy of the object: Wnet = Kf - Ki This relationship is called the work energy theorem W = Fdcosø When the energy of the body increases‚ work is positive. Examples: 1. A boy pushes a 5.00 kg cart in a circle‚ starting at 0.500 m/s and accelerating to 3.00 m/s. How much work was done on the cart? Answer: W= Kf- Ki = (0.5)m(vfinal)2 - (0.5)m(vinitial)2 W = (0.5)(5.00)(3.00)2 - (0.5)(5.00)(0.500)2 W =

The reason that a color change occurred when KI was added to the solution was because KI is ionic and when it was added to Red #2‚ the molecules dissociated causing the color to change. Also‚ due to the fact that when ionic solutions are added to nanoparticles‚ they clump together and cause a color change‚ we can conclude
