- Q: Have you Read it ? If SoCan You Think Of Any Good Group Discussion Questions ?
- Discussion and Essay Questions What is a catalyst? Who are the catalysts in this book? Why? What is Kate running from? How did she get lost (literally and figuratively)? Why does Kate hate English class? What are some of the myths surrounding the college application process? About high school? About kids like Kate? Kids like Teri? Find the list of vocabulary words given out for homework in Kate's English class. The author deliberately chose them. What is their significance? Why do authors do things like that? Does this make you hate authors? (joke... just wanted to see if you're paying attention) Discuss these image systems (symbols) found in the book: a. chemistry b. periodic table c. vision/sight d. movement vs. being stuck e. electricity What examples of safety awareness and danger can you find? How are they connected to each other? Make a list of all the elements and chemical terms used as chapter headings in the book. Explain how the chapters headings refer to the action with each chapter. Find the hints of Alice in Wonderland in the book. How does the story of Alice's journey reflect Kate's? Catalyst takes place in Merryweather High School, also the setting for Speak. What connections link the two books? How is food used in this book? Why don't we learn more about the life of Teri Litch (hint: examine the book's POV) How is Kate's relationship with her father? Why is it that way? Does it change over the course of the book. (Give examples for each answer.) Discuss the role of religion in this book. What does Kate believe in? Teri? Mitchell? How and why does Kate's relationship with Teri change after Mikey's death? Why are the three sections of the book labeled Solid, Liquid and Gas? Who is the most important character in this book? Why? How do the characters in Catalyst deal with defeat?
- Q: Who knows hydrogen and nitrogen in the high temperature, high pressure and catalyst conditions for the synthesis of ammonia chemical equation ah? Urgent! The SOS
- 3H2 + N2 ===== 2NH3
- Q: Does the catalyst slow down the chemical reaction rate? Still can only accelerate
- As far as I know, depending on the definition of the catalyst to reduce the activation energy can only accelerate the reaction rate. However, some substances can reduce the rate of reaction, for example, to dilute the reaction solution to slow down the reaction rate, but slow down the general mention of the catalyst.
- Q: The future direction of employment how, in what kind of units to do what work, how the closure rate? The
- Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.
- Q: What is the standard for the storage of flammable and explosive chemicals now?
- First, the basic requirements of classification of storage Dangerous goods, variety, complex performance, storage, in accordance with the zoning, classification, sub-section of the principle of special storage, set the number, set the number of fixed warehouses, fixed staff (four) custody. Small warehouses should be classified, divided, sub-stack storage, the performance of each other, fire fighting different items, dangerous dangerous goods and other general dangerous goods, should be stored separately.
- Q: what is the difference between enzyme and catalyst?
- Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
- Q: Please name 2 common examples of catalysts.Thank you?
- Easter in making Curd fermentation.Sodium bi carbonate in faster flour formation. these are used in the domestic kitchen mostly.
- Q: How to poison the catalyst. What can be done?
- In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
- Q: In biology, the enzyme seems to be a tool for opening a reaction, such as the decomposition of cellulose, such as linked RNA and protein, no enzyme can not. But in chemistry, the catalyst is only a regulatory role, change the reaction rate only. The teacher said that the enzyme is the catalyst. Is there any other effect of the enzyme? (Ignorant high three dogs, you do not spray the big god)
- I do not know the main high school teachers have done with fresh chicken liver grinding solution and ferric chloride solution compared to the decomposition of H2O2 catalytic efficiency of the experiment, the result is ferric chloride plus H2O2 slowly take the bubble, add fresh chicken cups Quickly take bubbles and liquid spill. Indicating that the enzyme is a catalyst, and the catalytic efficiency is far higher than the inorganic catalyst.
- Q: An important property of the catalyst is that the reaction equilibrium is not changed while increasing the forward reaction rate and the reverse reaction rate. However, because the enzyme for the specificity of the substrate, is not almost every reaction by the enzyme are one way to do it.
- A brief description of restriction endonucleases and DNA ligases: Restriction endonucleases, and DNA ligases, can be said to have nothing to do with energy calculations. In particular, the actual effect of these two enzymes is not to switch between A (DNA) and B (disconnected DNA) states. Restriction endonucleases do not need to open base pairing in addition to the phosphates, whereas the DNA ligase itself is responsible for linking 5'-phosphate and 3'-hydroxy. Which use the energy supply substances, coenzyme are not the same, can not be used as the same reaction is positive and negative process considerations.
