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

B. combustion

Explanation:

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.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

it is a good conductor
