Plz hurry it's urgent! which is the correct balanced equation that shows the process of iron oxide (fe2o3) explosively combining with aluminum (al) to produce iron (fe) and aluminum oxide (al2o3)? a. fe2o3 + al → fe + al2o3 b. fe2o3 + 3al → 3fe + al2o3 c. fe2o3 + 2al → 2fe + al2o3 d. 2fe2o3 + 2al → 2fe + 2al2o3

C.  Fe2O3 + 2Al → 2Fe + Al2O3
