Aluminum can react with oxygen gas to produce aluminum oxide (Al2O3). What type of reaction is this? A. single replacement

B. combustion
C. double replacement
D. decomposition

Answer 1

B. combustion would be the correct option

Answer 2

Answer: B. combustion

Explanation:
`2Al+3O_2\rightarrow 2Al_2O_3`

A. Single replacement: A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

B. Combustion: is a chemical reaction between a substance and an oxidant usually atmospheric oxygen accompanied by generation of heat and light.

C. Double replacement: A double replacement reaction is one in which exchange of ions take place.

D. Decomposition : is a reaction in which one reactant decomposes to give two or more than two products.
