Question

name substance oxidised,reduced, oxidusing agent , and reducing agent of Mg+O2-MgO , MnO2+Al to form MnAl2O3
, Al+Hcl to form AlCl3+H2​

Answer 1

Answer:

Al = 1 ,  H = 1 x 2 = 2,  cl =1 x 2 =2,  Al =1, H = 2 , cl = 3 , Al = 1 x 2 =2 , H = 1 x 6 = 6, Cl = 1 x 6 = 6 , Al = 1 x  2 = 2 , H = 2 x 3 = 6 , Cl = 3 x 2 = 6.

Explanation:

2 Al + 6 Hcl     2 Alcl 3 + 3 H2
