Q:High school chemistry, catalyst activation energy map
Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!
Q:Will the chemical catalyst not reduce that?
Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
Q:Why can some catalysts be reused in (chemistry)?
Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
Q:High school stage which organic chemical reactions do not use catalyst
Aldehyde and silver ammonia solution reaction, and the new system of Cu (OH) 2 reaction.
Q:Manganese dioxide can be used as a catalyst for various chemical reactions
The reactor may be a reactant,
Q:What is the catalyst in the end?
You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
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:Word editor when playing chemical equation = with the above conditions or how to adjust the size of the catalyst, how to make it centered,
Open the word - insert - object - WPS3.0 formula - and then select the "label arrow template", you can add a catalyst.
Q:How does the catalyst affect chemical balance? Why the catalyst has no effect on the chemical equilibrium, for v-t diagram
The catalyst only affects the time required to reach equilibrium and does not affect the conversion of the reactants
Q:Can Cuo react as a catalyst with H2O2, does its quality and chemical properties change?
Can be, please, upstairs said wrong ... ... ... ... ... ... catalyst is not not to participate in the reaction, the second is because the essence of the catalyst is to participate in the reaction to accelerate the reaction rate of conversion, the catalyst after the reaction will be regenerated, and before and after conservation, quality and Chemical properties do not change. CuO is the catalyst for H2O2 reaction, and the catalytic effect of CuO is better than Mn02!
