Answer 1

Seriously? No one is going to answer all 12 questions, but I'll do a few to hopefully show you the process.

1.)  FeS + 2HF ==> H₂S + FeF₂  This is double replacement. 

2.)  2Al(s) + 6HBr(aq) ==> 2AlBr₃(aq) + 3H₂(g)  This is single replacement. It is also a redox.

6.)  Na + I₂ ==>2NaI  This is synthesis.

7.)  2KClO₃ ==> 2KCl + 3O₂  This is decomposition

11.)  2C₂H₆ + 7O₂ ==> 4CO₂ + 6H₂O  This is combustion
