Translating Word Equations into Balanced Chemical Equations
• If a compound is ionic. . . YOU MUST balance charges!!!• You may need to do this in steps.
• Diatomic molecules• When these elements appear BY THEMSELVES, NOT IN COMPOUNDS, you
need to include the correct subscript.
Ex. Aluminum bromidePredicting Products Notes
SynthesisMg + O2 à
Al + N2 à
Decomposition• Binary ionic compounds break down into their elements.• Carbonates break down into an oxide and carbon dioxide.• Chlorates break down into a binary salt and oxygen.
K2O à
BaCO3 à
KClO3 à
3. Predict the products and balance Potassium carbonate ‐‐>

1. Aqueous iron (II) iodide reacts with liquid bromine to produce aqueous iron (II) bromide and solid iodine.
2. Aqueous potassium carbonate reacts with aqueous calcium bromide to produce a precipitate of calcium carbonate and aqueous potassium bromide.
Write the balanced chemical equation that actually occurs.
Use the activity series to determine which reaction occurs.
