what is a catalist?

Answer 1

i like burgars............and pizza too

mmm....arent there any cartoons yet???!!!

Answer 2

Any substance that speeds up a chemical reaction without being used up is called a CATALYSTS. They may be solids or liquids. I have not heard of gaseous catalysts yet.

They are neat and useful substances because you can use it again and again. That is why catalytic chemistry is very important in manufacturing. It saves the producers a lot of money and TIME. However, some catalyst may also be susceptible to "poisoning" - meaning that their effectiveness are compromised by other substances that degrade the ACTIVE site where the chemical reactions occur.

By the way the correct spelling is CATALyST, with a y not i.

Answer 3

Catalist is a substance which accelerates or retards a chemical reaction without itself participating in reaction. In biological reactions they are called enzymes.

Answer 4

A substance that changes the rate at which a reaction equilibrium is attained, without itself being consumed. Itdoes not appear in the final product and undergoes no permanent changes. Catalysts can increase the rate of reaction (positive catalysts) or decrease them (negative catalysts or inhibitors).

Answer 5

catalyst - (chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected

Answer 6

A catalyst is something that quickens the process of something else.

Answer 7

you mean CATALYST? Well catalysts are enzymes which hasten chemical reaction...

Answer 8

isn't that the stuff you put into bondo (plastic body filler) to make it harden?

Answer 9

its what you add that causes a reaction
