Here's a general representation:
A + B → AB
Where:
* A and B are the reactants (the starting substances)
* AB is the single product formed.
Examples of synthesis reactions:
* Formation of water: 2H₂ (g) + O₂ (g) → 2H₂O (l)
* Formation of sodium chloride: 2Na (s) + Cl₂ (g) → 2NaCl (s)
* Formation of carbon dioxide: C (s) + O₂ (g) → CO₂ (g)
Key features of synthesis reactions:
* Two or more reactants combine to form a single product.
* The product is more complex than the reactants.
* Energy is usually released (exothermic reaction).
