and the sodium hydroxide. When using glassware in experiments‚ it must be flushed out to make sure that cross contamination does not happen and that the only thing that would then be coating the beaker is the distilled water. When all of the glassware has been cleaned‚ some sodium hydroxide should be placed in a plastic weighing boat next to the scales and place the second weighing boat on the scales and weigh it then click the on tare button to set it back to zero and weigh out 1g of sodium hydroxide

Experiment 7 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction: The student will perform the experiment in order to find the percent yield by using the theoretical value found using the balanced equation for sodium carbonate as well as sodium bicarbonate. The objective is to stabilize the substances by titrations and finding the percent yield when all the data is collected. The purpose of this procedure is so that the student will get better understanding of stoichiometry

Justin Pawlyna ENGL 102 – AS85 E-cigarettes and Harm Reduction Should our current approach to combat tobacco addiction focus on abstinence or harm reduction? Many believe the only way to avoid the dangers of smoking is complete cessation. With so few choices‚ most smokers today would rather continue smoking. Electronic cigarettes‚ also known as "e-cigarettes" have sparked new debate about harm reduction. Smokers have found an alternative to traditional cessation methods that are ineffective. In my

There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In some foods the ingredients include chemical compounds as sodium nitrate and potassium bromate. Sodium nitrite is an ionic compound and is identified by the chemical formula

PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol
