A) an atom seeks to fill its outer shell of electrons
B) an atom seeks to balance its positive and negative charges
C) the reaction will result in paired electrons
Explanation;
-In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
-During a chemical reaction an atom may lose of gain electrons resulting positive and negative ions (ionic bond formation) or may result to the paired electrons (sharing of electrons).
I may be wrong but I think it’s the second one. They speed up reactions, and there’s a certain enzyme for a certain reaction.
