oxygen released for the cold trial was 38 mL‚ 11 mL less than the control. Conclusion: The hot trial produced the most oxygen of all three trials. Heat tends to increase the rate of chemical reactions‚ explained in the article Temperature Effects (Introduction to Enzymes) by Chris Jamison. “Like most chemical reactions‚ the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree rise in temperature will increase the activity of most enzymes by 50 to 100% . Variations

reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

System (SJHS)‚ risk management is considered the responsibility of every SJHS associate‚ from the CEO to the maintenance man. Each associate has an obligation to perform their jobs safely and to eliminate or at least minimize the risk of harm to any resident‚ visitor‚ or employee. The collection and utilization of data is also essential to a successful risk management program. Effective risk managers recognize the importance of data which may be used to identify residents at risk for falls‚ wounds

1. In what way(s) is Tiffany exposed to exchange-rate risk subsequent to its new distribution agreement with Mitsukoshi? How serious are these risks? Answer: About 15% of (1992) sales of $492mln or ~ $75mln will now be earned in Yen‚ but will have to be reported in $. At a Net Income (1992) of $25mln‚ the risks caused by this exposure are significant. Data from exhibit 6 shows that in a 6-month period (Apr-Sep) exchange rates fluctuated as much as 10%.

reactions; therefore‚ enzymes are able to speed up these reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed reaction is reduced or can be stopped if the temperature becomes too high. This is due to the fact that enzymes become

The Earth - it’s an intricate formation of land and sea‚ rock and metal‚ but how can the movements of the continents be explained‚ or how do deep ocean trenches affect us? The three main theories that explain how these things work are sea-floor spreading‚ continental drift‚ and plate tectonics. These are the theories that give us explanation as to why the continents move‚ how plate tectonics work‚ etc. These theories were formed by different scientists and with different forms of evidence‚ some scientists
