Q:catalyst..........?
Short=yes they are. Long version Traditionally, acids were defined to be compounds that produce H+ ions when dissoved in water (Arrhenius theory). But this definition is limited to acids that can be dissolved in water. Brønsted-Lowry then formed a definition which states that acids are compounds which donates a protons or H+ ions. If u think about it, a H+ ion is practically a proton. a proton with no electron outer shell is far too reactive to stay in its current state. thus it will form a bond with H2O to form H3O+ Because of this, acid catalysts are supose to be H3O+ instead of H+. But since it is more convinient to use H+, the form of writing H+ remained instead....... and yes...... the scientists were lazy......
Q:Why is the catalyst in the chemical balance, the rate of change and balance?
Plus the catalyst, but only to change the activation energy of the reaction, so that more molecules at the same time to participate in the reaction.
Q:Nitrogen and hydrogen in the role of high temperature and pressure catalyst to generate ammonia chemical equation
N2 + 3H2 = catalyst, high temperature and high pressure = 2NH3
Q:How do enzymes / catalysts in biology and chemistry in high school stage give different feelings?
I do not know the main high school teachers have done with fresh chicken liver grinding solution and ferric chloride solution compared to the decomposition of H2O2 catalytic efficiency of the experiment, the result is ferric chloride plus H2O2 slowly take the bubble, add fresh chicken cups Quickly take bubbles and liquid spill. Indicating that the enzyme is a catalyst, and the catalytic efficiency is far higher than the inorganic catalyst.
Q:What kind of chemical reaction requires a catalyst?
For example, the system of ammonia, S02 oxidation into SO3
Q:Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen
2KMnO4 = Δ = K2MnO4 + MnO2 + O2 ↑
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
In the chemical equilibrium, after adding the catalyst, the positive and negative reaction rate increases equally, but the positive reaction rate is still equal to the reverse reaction rate, so the balance does not move
Q:Which chemical reaction is added to the catalyst in order to slow down the reaction
Edible oil added 0.01% to 0.02% gallate n-propyl ester, you can effectively prevent rancidity
Q:What about the chemical reaction of the catalyst if there is no catalyst?
The catalyst used to heat and hold, the material will not react between.
Q: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.
