Chemistry Writing Reactions (Step 1)
Name______________________________________
Please write a complete balanced reaction for each one, using state symbols. Then identify the
reaction type.
State Symbols:
(g)
(l)
(s)
(ppt)
(aq)
gas
liquid
solid reactant
precipitate = solid product
aqueous = dissolved in water = solution
heated, not burned
Example:
Chlorine gas is bubbled through a solution of aluminum iodide to produce solid
iodine and a solution of aluminum chloride.
Answer:
3 Cl2 (g) + 2 AlI3 (aq) → 3 I2 (ppt) + 2 AlCl3 (aq)
