Q:How does the catalyst for organic synthesis look for?
No other, is the test, so I put the pit out of the theory ... ...
Q:How does the catalyst affect chemical balance?
The mechanism of the catalyst is to affect the reaction activation energy in the reaction. The positive catalyst reduces the activation energy required for the reaction and increases the proportion of the activated molecules, thus reducing the reaction time.
Q:Carbon dioxide and hydrogen in the catalyst and heating conditions
CO2 + 4H2 = catalyst, heating = 2H2O + CH4
Q:Explanation of Catalysts?
A catalyst is a compound in chemistry (it can be an acid or temperature or a base or a metal or anything, pressure anything) that shifts the reaction towards one product or the other... In simple words. If you want to obtain something, e.g. water, then you can obtain it in different timings, ie in 2000 years, but if you want to obtain it in 2 hours instead of 2000 years then you add a catalyst, e.g. you heat the reaction to speed it up, you add an acid, or a base etc. Some catalysts also act on the regioselectivity of a compound thru preferring the formation of a stereo-isomer to another. E.g. if you want to obtain S-Thalidomide instead of R-Thalidomide you use a particular catalyst etc...
Q:The concept of catalyst in high school chemistry
The catalyst is selective, that is, a catalyst that catalyzes only one or more chemical reactions and does not catalyze all chemical reactions. However, a chemical reaction of the catalyst may be a variety of, such as hydrogen peroxide to produce oxygen in the reaction, in addition to the use of manganese dioxide as a catalyst, you can also use copper oxide, iron oxide as a catalyst. Building on the use of cement, red brick powder also catalyze the decomposition of hydrogen peroxide.
Q:give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
I like the hydrogen peroxide answer, but I just ran out of MnO2 at my house, I guess I will just have to pour some H2O2 into the small cut I have. The bubbles you see are oxygen gas which is formed by the decomposition of the H2O2 catalyzed by the peroxidase enzyme in your blood.
Q:The best use of chemical catalysts
Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
Q:Chemical equation if there is a catalyst and heating, which write in the equal sign above
At the same time, the catalyst is written on, and the heating symbol is written under the equal sign. Only one is written on the equal sign
Q:Which of the following are true about catalysts?
1. Catalysts can help to bring the reactants together in the correct orientation False. It provides an alternative pathway (of lower activation energy) for reaction to occur. 2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation. False. Written on the arrow that show the reatctants becoming products. 3. Catalysts can provide a surface on which the reaction occurs. True. For instance platinium in the case of hydrogenation of alkenes.
Q:What is a catalyst and what is it do?
by lowering the activation energy
