- Q:Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
- In fact, the catalyst in the reaction process has become other substances, but after the end of the reaction, the catalyst has changed back. That is, the catalyst is actually involved in the reaction, except that the amount of catalyst being reacted is as much as it did.
- Q:How does the chemical equation calculate the quality of the catalyst?
- Catalyst, the quality of the reaction before and after the same, the same chemical properties.
- Q:What is the definition and function of the catalyst in chemistry?
- The catalyst plays an important role in chemical production. For example: in the oil refining process, the use of high-performance catalyst into gasoline and no other; in the car exhaust treatment process, with the catalyst to promote harmful gas conversion ...
- 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:hey people i need your help about my science lab report...the question on my paper says "what function the catalyst?....please help me on this one...i would really appreciate if you leave me answers....much mahalos to all you folkss...thanks
- concepts-blowing on Bandit - it converts Carbon monoxide into Carbon Dioxide (besides as emitting risky debris of Platinum, Iridium and tungsten). hang on - Carbon Dioxide - isn't that the ever so nasty greenhouse gas that we are all meant to be reducing our output of? i'm taking my cats off.
- Q:the heterogenous catalyst ZSM-5 IS used to convert ?
- Zeolite-based heterogeneous catalysts are used by industrial chemical companies in the interconversion of hydrocarbons and the alkylation of aromatic compounds. A very good example is the zeolite ZSM-5. This zeolite, developed by Mobil Oil, is an aluminosilicate zeolite with a high silica and low alumininum content. Its structure is based on channels with insecting tunnels. The aluminium sites are very acidic. The substitution of Al3+in place of the tetrahedral Si4+ silca requires the presence of an added postive charge. When this is H+, the acidity of the zeolite is very high. The reaction and catalysis chemistry of the ZSM-5 is due to this acidity. The ZSM-5 zeolite catalyst is used in the petroleum industry for hydrocarbon interconversion. An example use is in the isomerizations of xylene- from meta to para-xylene. The acidic zeolite promotes carbocation isomerizations. There are two suggested mechanisms for this type of isomerizations. Firstly shape may play a role. Perhaps para-xylene has a shape which allows it to diffuse rapidly through the zeolite structure, whereas as meta-xylene takes longer to pass through the zeolite and thus has more opportunity to be converted into the para-xylene. Secondly, is that the orientation of reactive intermediates within the zeolite channels favors specifically para-xylene.
- Q:What are the methods of catalyst characterization?
- Catalyst characterization is through the physical or chemical detection test means, the structure and nature of the catalyst to give a state description, to help explain the characteristics and characteristics of the catalyst,
- Q:describe a biological catalyst?
- A biological catalyst is the almighty enzyme. An enzyme takes the food that animals eat, yes including you, and breaks the raw stuff into more tangible byte sizes pieces for all the cells of a living organism. So essentially a catalysts is a mover of a biological system. Whole systems such as the apex predator the great bald eagle. I think the whole system catalyst are the decomposer organisms. The little crawlers like shredders and mushrooms. I hope that this helps
- Q:in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks
- The question was for bank 1 and the code is for bank2.Toadyboy is correct.Follow his lead.
- Q:What is catalyst in Science?
- A catalyst is a substance that increases the rate of a reaction by decreasing the activation energy (energy required to start the reaction). It does so by creating a new reaction mechanism (the way the reaction happens on a molecular level) that happens more easily and with less energy. For example, a catalyst could attract both reactants, thus bringing them directly together and facilitating the reaction.
