Answer:
hello the options related to your question is missing hence I will give you a general answer as regards to combination of atoms in a chemical reactions
answer :
In a chemical reaction the bonds that are found between the atoms of reactants are broken up and a different/new bonds are formed between the atoms of the various reactants involved in the chemical reaction to produce a new product. during this process no new atoms are created but new bonds are created to form a product
Example of such substance where atoms can combine together in a chemical reaction is : Iron sulfide [ Fe(s) + S(s) → FeS(s) ]
