- Q: Chemical catalyst system baa?
- Catalyst is divided into inorganic catalyst and organic catalyst organic reaction generally need more catalyst, such as concentrated sulfuric acid
- Q: Does the catalyst participate in chemical reactions?
- The catalyst only acts as a catalyst in the chemical reaction and does not participate in the chemical reaction
- Q: Is the catalyst in the field of inorganic chemistry?
- In particular, the chemical and homogeneous catalysis of inorganic chemistry has deep origins. Inorganic chemistry, oxides (such as metal oxides), family elements (such as the chemical behavior of transition metal elements) can be provided for catalytic science Support and guidance.
- Q: What is the quality of the catalyst in the chemical reaction, for example, 34.3 g before the hydrogen peroxide reaction, 32.7 g after the reaction, and how much is the catalyst mass?
- You can not calculate this question, the quality of the catalyst before and after the same reaction, how much reaction before the reaction on how much
- Q: What is the reaction of hydrogen peroxide to add manganese dioxide?
- There are bubbles produced
- Q: What is the difference between a catalyst and an oxidizing agent?
- A catalyst is a substance that increases a chemical reaction rate without being consumed in the reaction. Heat is probably the most common catalyst. In some cases the reaction will occur without the catalyst but very slowly. In other cases, the reaction will not occur. In the body, enzymes are often catalysts. An oxidizing agent, causes a compound to lose electrons and it is then said that that compound was oxidized. The oxidizing agent gains electrons and is said to be reduced. An example is hydrochloric acid. Is is oxidized by oxygen gas and loses hydrogen atoms leaving chlorine gas. The oxygen gains hydrogen atoms and forms water. The hydrochloric acid is oxidized and the oxygen is reduced.
- Q: Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
- can only change the rate of chemical reaction, do not change the equilibrium point of the chemical reaction, the enzyme itself does not change before and after the chemical reaction (3) can reduce the chemical reaction of the activation energy The
- Q: A substance involved in chemical reflection, but reflects the quality of the material before and after the change, you say it is a catalyst?
- Is a catalyst. The catalyst is actually involved in the reaction, (these are multi-step reaction), but in the final time from the reaction out.
- 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: put in a way that a freshman in high school can understand please =)
- Enzymes are actually biological catalysts composed of hundred of amino-acids, which are produced by living organisms. They are responsible for a number of reactions and biological activities in plants, animals, human beings and micro-organisms. There are also chemical catalysts that interact with other reactants and modify them without being changed themselves.
