What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
- This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know yous
Could God be Discribed as a Catalyst?
- It depends on the context. A catalyst for what? A catalyst being (from a scientific point of view anyway) something that speeds up the rate [of a reaction] without itself being altered. In that respect you could view God as being a catalyst for war, or religious hatred. The counter argument being that it is religion (ie. the interpretaion of God) which is the catalyst. And not to be too negative, God could be seen as a catalyst for good; many of the charitable organisations in the world are theistic in some way. Point is, I'd say that religion, rather than God himself, is the driving force. I don't believe in God, but I ain't, like, zealous about it.s
What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Hundreds of years ago the news once the industrial production and emissions of ozone generated less way, the ozone layer will still be thin.s
What are the catalysts?
- The relationship between it and the reaction system is as highly selective (or specific) as the relationship with the key. A catalyst does not catalyze all chemical reactions, such as manganese dioxide in the decomposition of potassium chlorate Play a catalytic role to speed up the chemical reaction rate, but the other chemical reactions do not necessarily have a catalytic effects
Please help - question about catalysts !?
- Catalysts are efficient at converting starting materials to the final products. Since catalysts convert these materials to the product faster, less energy will be used, and often less other materials will be used to complete the process. Both will save the company save time and money. Not to mention the catalyst can be reused, often hundreds of times before it needs to be replaced. Hope that helps!s
What is the catalyst called?
- Junior high school book definition: in the chemical reaction can change the chemical reaction rate of other substances, and its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. The role of the catalyst in the chemical reaction is called catalysis.s
What is the role of the catalyst in chemical knowledge?
- Reduce or increase the energy required for the reaction, can also slow down, do not have no effect on the reactions
Chemistry: Does the catalyst participate in the reaction?
- The catalyst does not participate in the reaction, except that the reaction rate is changed.s
