Answer» Answer: 20g of AL = 20/26.98 MOL = 0.74 mol 30G of S = 30/32.07 mol = 0.94 mol so, only min(.74/2,.94/3) = 0.31333 mol of Al2S3 can be formed: .31333 mol Al2S3 = .61667*26.98g Al + .94*32.07 g S = 16.64g Al + 30g S That leaves 3.36g Al unreacted6 by fhyrh hu dozoo xxxii do soCo xxxii DJ Di dogo do FU FIGHTING for you guys |
