Question

match the chemical reactions with their properties. 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:

1. Synthesis reactions combine two or more reactants to form one product.
2. Decomposition reactions break down one reactant into two or more products.
3. Combustion reactions involve oxygen as a reactant and release a large amount of energy.
4. Replacement reactions have one or more atoms replacing part of a compound.
5. Neutralization reactions between an acid and a base produce salt and water.

Answer:

1. The reaction has at least two reactants and one product. $\to$ synthesis
2. The reaction has one reactant and at least two products. $\to$ decomposition
3. Oxygen is one of the reactants, and a large amount of energy is released. $\to$ combustion
4. One or more atoms replaces a part of a compound. $\to$ replacement
5. The products are always salt and water $\to$ neutralization
