A catalyst helps with chemical reactions. Catalysts don't undergo any reaction themselves. The opposite of a catalyst is an inhibitor.
A substance that helps chemical reactions is called a catalyst. It speeds up the rate of a reaction by providing an alternative pathway with lower activation energy. Catalysts are not consumed in the reaction and can be used repeatedly.
Chemical reactions are chemical processes.
an element
Luminescence is caused by chemical reactions within the substance.
endothermic and exothermic reactions
energy
enzymes carry out chemical reactions, and enzymes are in proteins, so preoteins carry out chemical reactions
This substance makes up the majority of your cells, and is necessary for them to carry out most of their chemical reactions.
an enzyme
A catalyst helps chemical reactions occur.
Chemical reactions are chemical processes.
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
Produt!(:
A substance which helps with chemical reactions, by making them possible at all, or reducing the effort required, is a catalyst.
enthalpy
catalyst
Enzymes
a substance that is formed in a chemical reaction is called a product=)After a chemical reaction, new chemicals are formed. For an example:-NaOH + HCl = NaCl + HOH(H2O)Chemical substances are formed in chemical reactions.
