- Q:Palladium is the main catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on. While the most common and most commercially available palladium jewelery is palladium.
- Q:What is catalyst in Science?
- Like everyone told you, catalysts increases the rate of reaction without being consumed. An easy example to think of is mixing natural gas with air --(CH4 + O2). The minute you mix them they are reacting , releasing CO2 as a byproduct and H2O. But they are reacting very slow. But take a match to that slow reaction and it instantaneously reacts with an explosion. In this case the match was the catalyst. It sped up the reaction without adding anything to the reaction or being consumed
- Q:how do catalysts help in green chemistry?
- Catalysts reduce the energy barrier for reactions, meaning they require less energy to make the forward reaction go. This means less heat, light, or other energy sources are required to perform the same reaction without a catalyst. Also, by definition, a catalyst is not consumed in a reaction and can therefore be recycled many many times before replacement is necessary.
- Q:It's a GCSE Chemistry questionI just need to know why there are so many
- Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
- Q:Please help me
- enzymes are like chemical scissors that break up starch inside your body they work best at 37'c which is body temperatur i think they are in the stomach? don't know for sure hope this helped as for catalysts i dont know
- Q:What is the analytical principle of chemical adsorbents? How about the number of active catalyst centers tested?
- What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
- 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:chemistry subject
- Catalyst is the substance used to enhance or reduce the speed of a reaction.. there are thousand of catalyst used..(product of one reaction may act as catalyst of another).. you can see in google
- Q:Chemistry teaching and learning a bit difficult, thank you
- 2NO + 2CO = 2CO2 + N2
