A molecule
is two or more atoms held together by a covalent bond (like H2O). I don't think it matters if it's in a chemical reaction or not, a molecule is a molecule.
On a side note, atoms held together by ionic bonds (electrons are transferred from one atom to another) do not get classified with the title molecule, but are simply called ionic compounds (NaCl or table salt is an example).
This is a chemical decomposition reaction.
The molecule that starts a chemical reaction is called a reactant. It interacts with other reactants in the reaction to form products.
A substance or molecule that participates in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that undergo a process of transformation to yield products.
A chemical reaction changes the actual chemical make-up of a molecule while a physical reaction only changed the physical state of a molecule, the atomic make-up in the molecule stays the same. (ex: H20(l) ---heat--> H20(g))
Reactant
A chemical reaction.
The representation is CO2(g).

In organic chemistry, an activator is a molecule that increases the rate of a chemical reaction, while a deactivator is a molecule that decreases the rate of a chemical reaction.
Yes, a molecule is the smallest unit of a substance that retains all of the chemical properties of that substance. In a chemical reaction, molecules may rearrange or combine with other molecules, but they themselves are not broken down into smaller parts.
A molecule that speeds up a chemical reaction is called a catalyst. Catalysts work by reducing the activation energy needed for a reaction to occur, which increases the rate of the reaction without being consumed in the process.
