  • Synthesis Reactions: Definition, Examples & Chemical Equations
    The reaction in which two or more substances react to form a single substance is called a synthesis reaction or combination reaction.

    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).
