Which group of elements are often used as catalysts?
A catalyst is anything which causes a chemical or physical reaction. As such almost anything other than the most inate chemicals could act as a catalyst.
What are the advantages of using a catalyst on and industrial reaction?
In the chemical industry and the industrial research, catalysis play an important role.The different catalysts are in constant development to fulfill economic, political and environmental demands.When using a catalyst it is possible to replace a polluting chemical reaction with a more environmental friendly alternative. Today, and in the future this can be vital for the chemical industry.The catalysts could help in accelerating chemical reactions and/or making it possible at lower temperatures.
When most chemical reactions take place some in the reactants must be broken a process that requires energy?
Catalysts
Does chemical reactions need water?
Yes, most chemical reactions involved in metabolism do require water.
What chemical reactions are most common to break down the molecules?
These are decomposition reactions.

Catalysts
Why are catalysts used in the production of ammonia?
Catalysts are just enzymes. They are used to speed up reactions. They are used in the making of most chemicals.
Is manganese dioxide a catalyst?
Enzymes are boilogical catalysts or assistants that speed up chemical reactions with out changing all enzymes are catalysts but not all catalysts are enzymes.Manganese oxide is not an enzyme but is a catalyst it is also a mineral. Thank you.
Which of the following statements about enzymes is not true A are catalysts B almost all enzymes are proteins C operate most efficiently at optimum pH D destroyed during chemical reactions?
Enzymes are not destroyed during chemical reactions.
What element speeds up chemical reactions?
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
Does chemical reactions need water?
Yes, most chemical reactions involved in metabolism do require water.
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
Where in a cell do most chemical reactions take place?
Most chemical reactions take place in the cytoplasm.
What are the key properties of enzymes and what is their function in biological system?
Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level, a cell is really a little bag full of chemical reactions that are made possible by enzymes! Enzymes are made from amino acids, and they are proteins. When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape. That shape allows the enzyme to carry out specific chemical reactions -- an enzyme acts as a very efficient catalyst for a specific chemical reaction. The enzyme speeds that reaction up tremendously.
What chemical reactions are most common to break down the molecules?
These are decomposition reactions.
