Aluminum can react with oxygen gas to produce aluminum oxide (al2o3). what type of reaction is this? single–replacement synthesis double–replacement decomposition

synthesis

Explanation:

1. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

Example:

2. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example:  

3. Double displacement reaction is one in which exchange of ions take place.  

Example:

4. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example:

the answer is c i believe
