- Q: What are the examples of chemical catalysts used in life?
- The use of new synthetic materials makes life more comfortable. Only wood, sand and grapes are natural building materials, but they need to be combined and protected with synthetic chemicals. Cement is a chemical product, As the adhesive used in the laminate and the metal used in the nail are chemical products, the glass is made by the chemist, and the improved product, such as heat-resistant glass (trade name Pyrex glass), becomes more tough. Paint is chemist design and creation, and many modern solid materials are also the same. Plastic is synthetic, they are used in kitchen and bathroom utensils, also used in the name of the product called Formica bakelite and its related materials, beverage bottles, Cutlery and utensils. Porcelain is made by chemists and used in kitchen and bathroom sinks and other fixtures. Metal is made of chemical changes made from ores. Aluminum was once a laboratory treasure, but used An electrochemical method, which now can be easily made from alumina, at least a portion of the carpet and decorative fabric used for the use of synthetic fibers and synthetic dyes to color. Freezer and air conditioner with special chemicals as coolant ; Gas and gas stoves can be used syngas or natural gas, the combustion process is still the chemical change.Our room with gas or oil industry to produce fuel to heat, this fuel is from the natural crude oil refining and chemical We have made use of synthetic chemical products and materials made in the chemical processing industry, such as plaster or wall panels, outer panels and roof panels, as well as tiles and carpets, to heat our buildings. The stove itself and the distribution of heat The pipes are made of chemical products - metal, insulating materials and ceramics. The current enters the home through the copper wire of the outsourced insulator, both of which are products of the chemical processing industry
- Q: Is the catalyst in the field of inorganic chemistry?
- The catalyst is a branch of physical chemistry
- Q: What is the chemical nature of the enzyme?
- Enzyme is an amphoteric electrolyte, soluble in water, easy to precipitate at the isoelectric point, the enzyme activity-pH curve and the zwitterion of the enzyme. The enzyme is a high-molecular colloidal material, generally can not pass through the semipermeable membrane; Dissociation curve similar to the enzyme in the electric field can be the same as other proteins swimming; ③ lead to protein denaturation factors, such as ultraviolet, heat, surfactant, heavy metals, protein precipitants, etc., can make the enzyme failure; Protease hydrolysis and loss of activity.In addition, the most direct evidence is that all has been highly purified and crystallized enzyme for a primary structure analysis, the results indicate that the enzyme is a protein.
- Q: What is the catalyst condition in the chemical equation?
- I studied three methods ~ word which can be used to give me a mailbox to the word text to pass you ~
- Q: Seems intuitive that it wouldn't, but I dunno the qualitative difference between activation energy & Gibbs free energy. I'M TOO LAZY TO GOOGLE I GOTS STUFF TO DO
- A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
- Q: Could God be Discribed as a Catalyst?
- it is my understanding that a Catalyst will bring something together that is already created. God on the other hand, according to Judeo-Christian Theology, he didn't just bring it together, he created it. plus, if the Judeo-Christian God did exist, we would have to assume (because of archaeological and scientific evidence) that He is the God of the Bible and that he does play a role in the same of things.
- 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: Before and after the chemical reaction, the nature of the catalyst unchanged this statement right? Why?
- Chemical properties do not change better. Some properties of the catalyst may change before and after the reaction. If the experiment proves, the state of the catalyst before and after the reaction changes, and some changes from powder to powder.
- Q: I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
- your O2 sensor measures the amount of oxygen remaining in the exhaust gas after the combustion process. The left over oxygen reacts with the sensor to send an electrical signal to your vehicles computer. the computer can then adjust your fuel injector pulse width in order to maintain the proper 14.7:1 air/fuel ratio. Excessive exhaust gases are the usual culprit when catalatyc converters fail. Even so the O2 sensor is usually fairly cheap ($20-$30) and simple to replace. I would replace it as cheap insurance
