1. Will the Reaction Occur?

2. Reactions that ALWAYS Occur
Synthesis
Decomposition
Combustion

3. Will the Reaction Occur in Single
Replacement Reactions?
To determine if a reaction occurs, use the Activity Series Chart.
If single element is listed higher in chart, the reaction WILL
OCCUR!
An activity series chart shows which elements are more or less reactive than other elements.

4. Will the Reaction Occur in Single
Replacement Reactions?
Example:
K + LiCl → Li + KCl
Will the Reaction Occur? YES or NO
Potassium is BELOW Lithium on the Activity Series Chart.
Therefore, the reaction will NOT occur.

5. Practice Mg + Zn(NO3)2 Ca + LiBr → → Zn + Mg(NO3)2 Ca + MgCl2 →
YES
Mg + Zn(NO3)2
Ca + LiBr →
→ Zn + Mg(NO3)2 NO
NO • Cu + NaNO3 →
Ca + MgCl2 →
YES
Mg + CaCl2

6. YES • K + Al(NO3)3 → Practice Ca + CuBr2 → Cu + CaBr2 Al + KNO3
YES • Ba + HgCl2 →
Hg + BaCl2
Au + KNO3 → NO

7. Practice
YES
Zn + AgNO3 →
Ag + Zn(NO3)2 NO
H2 + CaF2 →

8. Will the Reaction Occur in Double
Displacement Reactions?
To determine if the reaction occurs, use the Solubility Chart.
In a Double Displacement Reaction, one product must be soluble
& one must be insoluble.
The insoluble solid that forms is called the precipitate.

9. Will the Reaction Occur in Double Displacement Reactions?
Example:
AgNO3 + KCl → KNO3 + AgCl
Using the Solubility Chart:
In KNO3, find the ANION (NO3−).
Notice (NO3) is under the SOLUBLE heading and it does not have
any exceptions. Therefore, KNO3 is the SOLUBLE product.
In AgCl, find the ANION (Cl−).
Notice (Cl−) is under the SOLUBLE heading, BUT (Cl−) does have an exception when bonded with Ag. Therefore, AgCl is the INSOLUBLE product
Will the Reaction Occur? YES or NO
