Generic Formula
A + B ? AB
Description
Two or more simple substances combine to form a more complex substance.
Reaction Type Analysis
Understanding synthesis
Key Characteristics
Look for two simple reactants forming one complex product.
Real-World Example
Rust formation: 4Fe + 3O2 ? 2Fe2O3
Balancing Tip
Start by balancing atoms that appear in only one reactant and one product. Leave Hydrogen and Oxygen for last, as they often appear in multiple compounds.
