PREDICTING PRODUCTS REVIEW SHEET
The following reactants already have balancing coefficients for their likely
products. Write the balanced products with states or "NR" if no reaction will take
place. Underneath each reaction tell which type of reaction is taking place.
There may be more than one.
1. Mg(OH)2 (aq) + 2 HNO3 (aq) 
2 H2O (l) + Mg(NO3)2 (aq)
This is Double Replacement. More specifically, this is the special type
called and Acid/Base reaction to form water. It is also called Neutralization.
2. 3 KOH
(aq)
+ H3PO4 (aq)  K3PO4 (aq) + 3 H2O (l)
Double Replacement – Acid/Base Reaction
3. 2 C8H18 (g) + 25 O2 (g) [excess]
Combustion

16 CO2
(g)
+ 18 H2O
(g)
4. Sn(C2H3O2)2 (aq) + H2S (aq)  2 HC2H3O2 (aq) + SnS (s)
Double Replacement – You may not know it but SnS is a solid so
this reaction will occur.
5. 2 NaI
6. 2 Zn
7. Na2O
(aq)
(s)
Br2 (g) 
