-Add in the + and ->

-Balance the reaction.

*Potassium reacts with iron(II) chloride produces iron and potassium chloride.

Answer 1

balanced chemical equations

1) 2 KClO3 --------------------> 2 KCl + 3O2

2)     4 P + 5 O2 ------------------> 2 P2O5

3)   2 Na   + 2 H2O -----------------> 2 NaOH + H2

4)   S8   + 12 O2 --------------------> 8SO3

5)   H2SO4 ---------------------> H2O + SO3

next anothe reaction :

Potassium reacts with iron(II) chloride produces iron and potassium chloride.

2 K   +   FeCl2 ---------------------> 2 KCl + Fe
