Predicting Products of a chemical equation

For this question you need to think whether Ag or Cl is the stronger oxidiser to see whether any reaction will happen.

If Ag is the stronger oxidizer then metal replacement will occur and you have to work out the chemical equation for Ag + O.

Thank you for posting your question to the Ask Me Help Desk.

Here are some general equations for 4 common types of reactions with examples that have not been balanced. You can use this as a guideline for determining products. There are other reaction types but in a beginning chemistry course in high school most of the reactions you work with will fall under one of these categories.

1. Synthesis

A + B --> C

H2 + O2 --> H2O

Sometimes written as

A + B --> AB

2. Decomposition

C --> A + B

H2O --> H2 + O2
Or

AB --> A + B

3. Single Displacement

A + because --> AC + B

Zn + HCl --> ZnCl2 + H2

4. Double Displacement/Precipitation

AB + CD --> AD + BC

Pb(NO3)2 + KI --> PbI2 + KNO3

Of course you want to remember rules for the formation of compounds and naming conventions as well.
