2. Yes, there is only one product is formed at the end of combination reactions.

Combination Reaction :

A chemical reaction in which two or more substances combine to form a single product is called a combination reaction or synthesis.

 When iron and sulphur are heated together, they combine to form a single product, iron sulphide.

                                   2Fe(s)     +     S(s)    →              FeS (s)

                                       Iron         Sulphur                Iron sulphide
