- 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: Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- 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: What is the catalytic efficiency of ordinary chemical catalysts?
- Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different
- Q: Why does the chemical and chemical properties change before and after the reaction?
- At present, the role of the catalyst has not yet fully understood. In most cases, it is believed that the catalyst itself and the reactants participate in the chemical reaction, reducing the activation energy required for the reaction. Some catalytic reactions are due to the formation of a very easy decomposition of the "intermediate", the decomposition of the catalyst to restore the original chemical composition, the original reactant becomes a product. Some catalytic reactions are due to adsorption, adsorption can only be in the catalyst surface of the most active area (called the active center) carried out. The greater the area of the active site, the greater the activity of the catalyst. Reactants such as impurities,
- Q: High school stage which organic chemical reactions do not use catalyst
- Olefins, alkynes, making bromine water, potassium permanganate fade.
- Q: What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
- Enzymes are a kind of catalyst.
- 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: Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
- Q: What are the characteristics of the catalyst in the catalytic reaction?
- The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
