- Q:What are the examples of chemical catalysts used in life?
- Clothing. "New synthetic fiber made of clothing, soft and comfortable and cheap and durable. Cloth from natural fibers to man-made fibers, and then to the development of synthetic fibers, dyes from the original natural dyes to the current synthetic dyes, reactive dyes , All reflect the contribution of chemistry to the development of clothing, chemical clothing from the initial cover utility, into today's beautiful, convenient, with a special function of the utility, it greatly enriched the style of clothing, material, use
- Q:give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- When making margarine, nickel is used to speed up the process.
- Q:In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
- 2H2O = (light or catalyst) 2H2 ↑ + O2 ↑
- Q:What are the catalysts for making oxygen in chemistry? (At least 8 listed)
- If the decomposition of hydrogen peroxide generated, as long as there are things that can be catalyzed by catalase
- Q:What is the standard for the storage of flammable and explosive chemicals now?
- First, the basic requirements of classification of storage Dangerous goods, variety, complex performance, storage, in accordance with the zoning, classification, sub-section of the principle of special storage, set the number, set the number of fixed warehouses, fixed staff (four) custody. Small warehouses should be classified, divided, sub-stack storage, the performance of each other, fire fighting different items, dangerous dangerous goods and other general dangerous goods, should be stored separately.
- Q:The future direction of employment how, in what kind of units to do what work, how the closure rate? The
- Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.
- Q:Chemical catalyst in several ways
- Some are composed of oxidative - reduced electricity, such as manganese dioxide catalyzed by hydrogen peroxide decomposition
- Q:What is a chemical catalyst?
- A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
- Q:Could you please explain it, i know they increase reaction rates but how?
- A catalyst lowers the activation energy (the minimum amount of energy needed for a reaction to take place). This means that the particles can react with less energy than they needed before the catalyst was added. (Think about it: if the government lowered the legal age to buy cigarettes, then more people could legally buy cigarettes. Similarly, if we lower the amount of energy needed for particles to react, then more particles can react). Also, a catalyst provides a surface on which the reaction can take place. This increases the number of collisions between the particles of the substances that are reacting.
- Q:Why can't catalysts make an unfavorable reaction favorable?Can anyone give me a relatively simple explanation for this?Thank you so much in advance!
- Catalysts, as enzymes, only change the activation energy (the energy the compound needs to gain to transform into products), they don't change the Gibbs energy values of reactants nor products. Therefore, if the delta G of the reaction is positive, it'll still need free energy to complete. They make a reaction complete faster than in normal conditions, but don't change the actual possibility for that reaction to happen. In the human body, a lot of reactions of catabolism have a positive G value and these reactions needs to get energy from other coupled reactions that have a negative value, so the total value is still negative. Many of them use hydrolysis of ATP to provide that energy, as its hydrolysis is about -30 kJ/mol in physiological conditions. I don't know what class you're in to ask this question, so can't really know if this answer is too simple or complicated for u... sorry in advance! Jo?l
