Investigating Factors That Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles

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

“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
