determine the rate of reaction under different circumstances. Different variables will be manipulated to discover their effects on a particular reaction. Changes in temperature‚ pH‚ and enzyme concentration are examples of factors that have the potential to affect the initial rate of an enzyme catalyzed reaction in a controlled experiment‚ whether it be speeding the reaction up or slowing it down. Part I of the experiment establishes a baseline that can be used to compare the results of part II and

CHEMICAL KINETICS RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant

Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more

P6–1 Interest rate fundamentals: The real rate of return Carl Foster‚ a trainee at an Investment banking firm‚ is trying to get an idea of what real rate of return investors Are expecting in today’s marketplace. He has looked up the rate paid on 3-month U.S. Treasury bills and found it to be 5.5%. He has decided to use the rate of change In the Consumer Price Index as a proxy for the inflationary expectations of Investors. That annualized rate now stands at 3%. On the basis of the information

What happened to the R-R interval and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents

The data collected from the number of each type of macroinvertebrate was calculated to determine the Modified Family Biotic Index‚ percent contribution of dominant family‚ and EPT Index number for each of the three collection sites. The number of organisms and families of macroinvertebrates along with the calculated data can be seen in Table 1. Other sets of data was recorded and compared to test the stream quality at Pricket’s Creek. The water temperatures (°C) were 16.76 ± 2.32 (mean ± St. Dev

Divorce and out-of-wedlock childbearing are now epidemic in American society. Both forms of disrupted families are harmful to children and to society. The children of single parents are more likely to do poorly in school‚ commit crimes‚ and become single parents themselves. In addition‚ the increase in single-parent families contributes to such social problems as poverty‚ crime‚ and a decline in the quality of public education. Divorce and out-of-wedlock childbirth are transforming the lives of

Homeostasis and how the body responds to exercise. This report will interpret the results of the practical activities that was done in order to monitor the changes in heart rate‚ temperature and blood pressure before and after exercise. Blood pressure is the measure of how much pressure is put on the walls of the blood vessels when the blood is pumped through them. This is measured in two parts‚ the larger number on top is known as the systolic pressure‚ this measures the pressure as the blood
