<span>In chemistry, a catalyst can speed up the reaction (or make it initiate easier) by altering the activation energy, lowering it enough to allow the reactants to react more easily. Some negative catalysts or inhibitors can do the same by increasing the activation energy.

Answer:
<h3>2Al+ Fe2O3 gives 2Fe + Al2O3. The given reaction is a redox reaction. As oxidation and reduction are taking place simultaneously.</h3>
Explanation:
like this...Identify oxidation and reduction with their agents:
<h3>•2Al+ Fe2O3 →2Fe + Al2O3</h3>
<h3>•Fe2O3 is reduced to Fe whereas Al is oxidized to Al2O3</h3>
<h3>In the above reaction:</h3>
<h3>Oxidizing agent:Fe2O3</h3>
<h3>Reducing agent:Al</h3>

it is a molecule* that can be joined with other molecules that are identical to form a polymer*
key words :
a molecule:
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
a polymer:
a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together
hope this helped, good luck in future studies !
