Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

CHEMICAL WASTE MANAGEMENT IN DEVELOPING COUNTRIES INTRODUCTION Chemical waste is managed in various ways‚ some which are environment friendly and some which are hazardous. It has effects on water supply‚ fertility of the soil‚ climate‚ health of individuals‚ et.c. What really matters is how well this waste is managed. Chemical waste management typically includes the collection‚ transportation‚ processing and recycling/disposal of chemical waste. In past times‚ it was the role of the country to

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method

“A brief history of chemical warfare” By Harold Maass For more than 2‚000 years. As early as 600 B.C.‚ the Athenians poisoned the wells of the Spartans‚ who later tried lobbing burning sulfur pitch over the walls of Athens‚ hoping to fill the city with toxic smoke. Genghis Khan used that same trick‚ catapulting burning sulfur pitch during his siege of fortified cities around A.D. 1200. Over the centuries‚ various armies put poisons on arrows and in bullets to make them more lethal. But it wasn’t

There are two useful numbers that you can compute with the EAC. One of them is called Estimate to Complete (ETC)‚ which tells you how much more money you’ll probably spend on your project. And the other one‚ Variance at Completion (VAC)‚ predicts what your variance will be when the project is done. ETC = EAC - AC €11‚ 507 – €5‚ 750 = €5‚ 757 (how much the rest of the project likely to cost) Since EAC predicts how much money you’ll spend‚ if you subtract the AC‚ you’ll find out

experiment provides some very important information concerning the reaction of different solutions on the chemical weathering of the rocks. By comparing the change in mass and composition of the rocks kept in distilled water‚ soda water‚ and different concentrations of vinegar‚ it could be concluded that the acidity of the solution was what played the prime role in the speed of the chemical weathering. The first cup‚ containing 50% vinegar solution‚ had a starting pH of 3 and a beginning mass of
