Those substances are called, "Catalysts".
The process by which matter is changed into new substances is called a chemical reaction. During a chemical reaction, atoms are rearranged to form different molecules with new properties compared to the original substances.
chemical reaction is when a substance is changed chemicaly but not physicaly
The substances that are changed in a chemical reaction are known as reactants. These reactants undergo a chemical change or transformation to form new substances called products through the rearrangement of their atoms.

Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
A process in which reactants are changed into one or more different products
You think probable to atoms.
They could be chemical or (thermo)nuclear processes.
It is a chemical reaction. Go to the Related Links
Though a nuclear reaction could be the answer to this question, it is more probable that a chemical reaction is the change of one or more substances into a different substance or different substances. (The changes in nuclear reactions normally include only a single element.)Examples abound. The elements hydrogen (H2) and oxygen (O2) combine in a chemical reaction to form water (H2O) in the following familiar reaction:2H2 + O2 => 2H2OWhen ozone (O3) breaks down spontaneously, it forms oxygen in the following reaction:2O3 => 3O2
No. these are the reactants, the products are what are produced by the reaction.
