Question

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

Answer 1

it's a redox reaction

Answer 2

most chemical reactions fall under one of 5 distinct patterns, and those you should set out to memorize:

synthesis: A + B → AB

decomposition: AB → A + B

single displacement: A + BC → B + AC

double displacement: AB + CD → AD + CB

combustion: CxHz + O2 → CO2 + H2O

the reactions aren't balanced, but that's easily done once you recognize the format

Answer 3

Answer 4

single replacement
combustion
double replacement
