Balancing Equations and Predicting Products Guided Practice

Attempt writing the products for the first reaction

Poll

Did you predict Ag₂CO₃ and KNO₃ as the correct products?

• Yes

• No

General Steps for Predicting Products Problems

1. Identify the charges for the ions in the reactants.

2. Swap alike! (i.e. switch cations with each other and switch anions with each other)

3. Correct/check the new chemical compounds created by the swap using their charges.

4. Balance the chemical equations.
