Purpose: This laboratory was performed to find the temperature change‚ heat of reaction‚ and enthalpy change for neutralization reactions. The temperature change was found by subtracting the initial temperature from the final temperature obtained. Heat of reaction is negative heat of solution. Heat of solution was found by using the formula qsolution = mCsΔT (m= mass; Cs= 4.184 J/g°C; and ΔT = change in temperature). The enthalpy change was found by dividing the heat of reaction by the number of

CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature up to 50oC speeds

Mikhail Kashtelyan The Consequences of a global temperature rise on arctic ecosystems Nowadays the climate is changing‚ in more exact words the global temperature is raising every year. Those climate changes may cause a lot of different disasters and brake of ecosystems. A place that is really endangered of global temperature rise is arctic. Arctic is a very big icy landmass that is located north of the Arctic Circle. Arctic contains a lot of different kind of species. If the icy landmass

‘Kinetics’ is the study of chemical reactions. The speed of a reaction can vary depending on many variables such as the nature of the reactants‚ particle size‚ concentration and temperature. For a chemical reaction to occur‚ there must be a collision between reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago‚ Democritus‚ who was a philosopher

course‚ companies have a huge appetite for information‚ and have encouraged the development of systems to produce‚ store‚ and analyze it. A recent study by Pitney Bowes‚ in Stamford‚ Connecticut‚ found that the average white – collar worker at a Fortune 1000 company sends and receives an average of 190 messages a day‚ in a variety of electronic and paper formats. "It has become completely overwhelming‚" says Sheryl Battles‚ executive director of external affairs at Pitney Bowes. She reported that trying

of α-amylose consists of long polymer chains of glucose units connected by an α (1-4) linkage. Amylopectin consists mainly of α (1-4) linked glucose residues but is a branched molecule with α (1-6) branch points every 24 to 30 glucose residues on average. As a result of the bond angles in the α (1-4) linkage‚ amylose actually forms a spiral much like a coiled spring. Amylose is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose

LAB ACTIVITY: Coastal and Continental Temperature Ranges ANALYSIS: 1) I can tell from the temperature curves that the cities are all in the Northern Hemisphere because it ranges from low to high then back to low again starting in January. 2) The city that has the greatest yearly temperature range is Bismarck‚ N.D. 3) The cause of the greatest range is because the location is located most near the pole. 4) The rates of heating and cooling do not differ much for New York

Average is OK‚ it gets by. But maybe you want to be more. You want to stop being average‚ but you don’t know where to start. If this is the case‚ there are a couple of simple things that you can do to lift yourself from the baseline set by those around you. Here’s How to Stop Being One of the Average Joes – and Start Getting Ahead 1) Get out of Debt It’s no surprise that the average American is in debt. In fact‚ 80 percent of households are sitting in liability. Sure‚ a lot of those families
