Q:Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen

2Na2O2 + 2H2O = 4NaOH + O2 ↑

Q:What is the meaning of catalyst in chemistry?

In the chemical reaction can change the reaction rate of chemical reaction (increase or decrease) without changing the chemical balance, and its own quality and chemical properties in the chemical reaction before and after the material did not change the catalyst.

Q:Please help me

catalyst are enzymes that increase the rate of a reaction. they both are proteins. so basically, a catalyst is an enzyme that increases the rate of a reaction.

Q:What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?

The enzyme has a high degree of specificity

Q:The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?

Catalyst before and after the reaction of the same quality,

Q:What are the catalysts?

The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This action is called catalysis. The reaction involving the catalyst is a catalytic reaction. The catalyst will induce a chemical reaction to change, causing the chemical reaction to become faster or slower or to undergo a chemical reaction at a lower temperature The catalyst is also known as a catalyst in industry, and the composition, chemical properties and quality of the catalyst itself do not change before and after the reaction;

Q:and can you give me an example of it .. please give it in easy terms if you can. thanks

the compound that allows for a chemical reaction. and example would be The enzyme catalase is the catalyst that allows hydrogen peroxide to break down into water

Q:give an example of how a catalysts speeds up the rate of reaction?? thank you!!?

Catalysts speed up a reaction, but at the end of it, it's chemically unchanged. You usually have the same mass at the end of the reaction. For example.. Consider the decomposition of Hydrogen Peroxide: 2H2O2 -2H2O + O2 I hope you got how to represent it =D So.. This reaction is very slow. You can try it out in the lab. So when we add a catalyst, the reaction speeds up. The catalyst used here is MnO2.. Manganese dioxide. Well.. The Enzymes in our body are also Catalysts. They speed up the Biological Reactions taking place inside out body. I hope this answers your question. :) Cheers

Q:Characteristics and types of catalysts?

Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
