Q: The properties of scandium: Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...

Q: Why is the catalyst in the chemical balance, the rate of change and balance?: But the positive reaction rate is accelerated, but also speed up the reverse reaction rate, the two increase the same multiple, so the system is still in a stable state, the same balance.

Q: Explain how a catalyst may increase the rate of chemical reaction?: Lowers the activation energy of the reaction. Like a hill, it makes the hill lower so the reaction can proceed faster and at lower temps. Delta G is lowered. Meaning less energy is needed to move the reaction forward. Catalysts (enzymes) are substrate specific. only specified compounds like a right glove only fits a right hand and not the left hand.

Q: What is the nature of the chemical catalyst?: Different reactions have different catalysts, mainly catalyzed, to speed up the reaction rate

Q: Why extract the genome, the digestion is always not cut: The specificity of enzymes is very strict, those compounds that are considered symmetric in organic chemistry such as glycerol, ethanol, citric acid, etc., are asymmetric (even with the same groups) when they are used as substrates for enzymes, That is, their location in space, after all, different (available "three-point landing" theory explained, 1948 Oqston proposed).

Q: I need to name 3everyday catalysts for my chemistry homework. I don't want anything complicated there must just be 3 easy ones out there... Then could you please state what each one is used for? Please do it like this, e.g.Hello ; used to say hi to someone. I know that's a bad example but please!!: Hello ; Chemical catalysts are substances that increase the rate of reaction (while remaining themselves chemically unchanged: Polyethylene, the polymer used to make everything from: 1. garbage bags and 2. grocery bags, to 3. squeezable bottles, to 4. cable insulation, is made by passing ethylene gas over a catalyst. Most other polymers are made in the same (or similar) way. Synthetic rubber, nylon, polyester, PVC, teflon, etc. It's not hard to think of 10 uses for these catalyst-produced materials alone... e.g. : 5. rain coats 6. pantyhose 7. water pipes 8. bouncy balls 9. non-stick surfaces and pads 10. saran wrap 11. food containers 12. cell-phone and laptop cases 13. cheap wigs 14. fishing line... 15. Enzymes are Biological catalysts: 16. beer and 17. bread are typically made with yeast, a living organism containing enzymes I hope this helps!

Q: In the chemical reaction will have to use the catalyst reaction, such as H2O2 === (MnO2) H2O + O2 ↑, then the catalyst in the end to participate in the reaction (that is, the catalyst itself is the reactant) If so, why are some of these substances in the reaction (these substances refer to the catalyst) in the reaction after the quality and nature of the change does not change?: In the chemical reaction can change the chemical reaction rate of other substances (both can also improve), and its own quality and chemical properties in the chemical reaction before and after the material did not change called catalyst (also known as catalyst)

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: how a catalyst can provide a new route in forming the product?: catalyst speeds up the reaction... i don't know if there is actually 'a new route' in product formation because catalysts should not affect the reaction... it only has to speed up the reaction
