Q:Why the catalyst after the chemical reaction of its quality and chemical properties unchanged

In fact, the catalyst in the reaction process has become other substances, but after the end of the reaction, the catalyst has changed back. That is, the catalyst is actually involved in the reaction, except that the amount of catalyst being reacted is as much as it did.

Q:In the presence of catalyst, KCl is produced in the thermal decomposition of KClO3.You did not have a catalyst. Did you get the same products for this reaction as you would have with a catalyst?

A catalyst changes the RATE of a reaction, not the products. So, yes, you get the same products without the catalyst as you do with the catalyst.

Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst

No need, because the catalyst in the chemical reaction before and after the quality of the same

Q:Is palladium predominantly a catalyst in chemistry?

Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on.

Q:What is the chemical nature of the enzyme?

The difference between the enzyme and the general protein is that the enzyme is a protein with a special catalytic function. Similarly, the enzyme, like other proteins, consists mainly of amino acids, with one, two, three and quaternary structures, and the same enzyme as other proteins The composition of the enzyme can be divided into two types: simple protein and binding protein. Some enzymes are only protein, its activity depends on its protein structure, such enzymes are simple protein; other enzyme active ingredients in addition to containing protein, but also There are some small molecules that cofactor, the two together to be active, such enzymes belong to the binding protein.The protein part of the protein is called the enzyme protein, non-protein part called the cofactor

Q:Name one case in which catalyst poisoning is useful?

alkynes can react with hydrogen in the presence of a catalyst such as palladium to form alkanes, if they catalyst is poisoned you can produce alkenes instead

Q:what is a catalyst?

a catalyst is a substance that affects the rate of rxn without actually being consumed in the rxns . a catalyst doesnt become a part of the products. catalystss are of two types 1 POSITIVE CATALYST . it increases the rate of rxn . that is the products are formed faster . eg sunlight in a photochemical rxn is a positive catalyst 2 NEGATIVE CATALYST - which slow down a rxn . like addition of glyceriene to hydrogen peroxide slows down its decomposition

Q:Horseradish enzyme catalyzed Luminol chemiluminescence reaction

Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached

Q:Can some chemical reactions have a variety of catalysts that are correct or wrong?

Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy

Q:Chemical production of iodine and magnesium with water as catalyst!

In the 250mL three bottles were equipped with spherical condenser and constant pressure dropping funnel, in the condensate tube connected to the anhydrous calcium chloride drying tube. The flask was placed with 1.5 g of magnesium chip and a small tablet of iodine, 10 g of bromobenzene and 30 mL of anhydrous ether were mixed in a constant pressure dropping funnel. First 1/4 of the mixture into the flask, a few minutes later see the magnesium surface of the bubble generated, the solution was slightly cloudy, iodine color began to disappear. If no reaction occurs, use a hot water bath. After the start of the reaction, stir, slowly dropping the remaining bromophene ether solution, dropping the rate to keep the solution was slightly boiling state, after adding, in the water bath to continue reflow 0.5h, magnesium tablets full effect.
