Question

neutralization combustion synthesis decomposition replacement
the reaction has at least two reactants and one product
the reaction has one reactant and at least two products
oxygen is one of the reactants, and a large amount of energy is released
one or more atoms replaces a part of a compound
the products are always salt and water

Explanation:

• "At least two reactants, one product" describes synthesis (combination of substances).
• "One reactant, at least two products" is decomposition (breakdown of a compound).
• "Oxygen reactant, energy released" is combustion (exothermic reaction with O₂).
• "Atoms replace part of a compound" is replacement (displacement of atoms in a compound).
• "Products are salt and water" is neutralization (acid-base reaction).

Answer:

synthesis, decomposition, combustion, replacement, neutralization
