This is a catalyst. A catalyst doesn't get destroyed during the reaction. Rather it's more of a reaction site where two substances can combine. One example of a catalyst is amyl alcohol, which can be used to produce pure potassium metal. However, it's destroyed during the process if there are impurities in the reaction because it's consumed in other reactions. Other examples of catalysts include catalase, platinum, and manganese(IV) oxide.
that substance is called a catalyst. Sometimes a catalyst can also decrease the speed..then it is specifically called negative catalyst....but if it speeds up the reaction it is called positive catalyst...but you could simply say "catalyst"
A catalyst. Though the chemical will undergo a change or changes during the reaction, it will finish the reaction as it started.
A substance that increases the rate of chemical reaction without suffering any permanent chemical change is a catalyst.
These substances are the catalysts.
That's a catalyst.

An Enzyme
A catalyst.
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
A chemical reaction means that when it has turned into the new substance it cannot be changed back. Once the compost has rotted it can't be changed back into eg: carrot shavings.
No. these are the reactants, the products are what are produced by the reaction.
For example, the change in the state of matter.
These are called catalysts.
These are called catalysts.
A catalyst.
It is called a reactant. While catalysts participate in reaction dynamics, they are not permanently changed in the process.
A substance that undergoes change in a chemical reaction is called a reactant.
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
No, enzymes are not permanently changed in the chemical reactions they are involved in. Enzymes are catalysts that facilitate chemical reactions by lowering the activation energy, and they remain unchanged after the reaction takes place. They can be used repeatedly in multiple reactions.

A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
chemical reaction is when a substance is changed chemicaly but not physicaly
You think probable to the reactants.
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
