To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order. Using

Pink 3 Orange No change 4 Orange Brown‚ Dark purple 5 Pink No change 6 Pink No change Conclusion: Electron affinity highest to lowest: Chlorine‚ Bromine‚ and Iodine. They are in this order because Chlorine reacted with both NaBr and NaI‚ Bromine only reacted with NaI and Iodine didn’t react with either of the other mixtures. Just the way how they reacted was how you could tell which was which. And

has a smarter packaging as compared to Blackbetty Dhamaka extra powder. * BLACKBETTY BLEACH VS OPEN BLEACH Blackbetty Bleach is far more better than open bleach when it comes to the brightening as well as cleaning‚ Blackbetty bleach has a light odor as compared to open bleach which makes it more likable. Packaging of Blackbetty bleach is more processed and convenient as compared to that to open bleach which comes in srcap pet bottles. * BLACK BETTY INSECT KILLING POWDER VS THE CAT Both

purpose of this lab was to determine the effectiveness of antiseptics‚ disinfectants‚ and antibiotics on bacteria. The hypothesis was that if bleach was used‚ it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro‚ erythromycin‚ and tetracycline for the antibiotics. All of these chemicals were used on the bacteria

were studied. Elodea was inserted into different beakers. One containing water and the other‚ bleach. The elodea was left unattended for an hour so that observations could be made to tell the difference in the results each beaker produced. After an hour the quantity of CO2 present was measured for the beaker with water and the beaker containing bleach. The results recorded were inconclusive because the bleach had a buffer that evidently lowered the pH‚ the beaker that had water in it showed signs that

will demonstrate how a chemical reaction from vinegar‚ water‚ and bleach can accelerate the rusting process of steel. If steel wool pads are submerged in bleach‚ water‚ and vinegar‚ then the steel wool pads will rust faster in water because Electrolytes accelerate the corrosion process when combined with water. Materials and Procedure: you will need: Steel wool pads (the soap-free kind) 3 Medium sized jars Water Vinegar Bleach Procedure: 1. Place the steel wool pad into the jar. 2. Fill
