What is the oxidation state for the atoms in the reaction:
2 Al + 8 H2O → 2 H+1 + 3 H2 + 2 Al(OH)4-

a) Elemental aluminum (Al) = 0 (zero)

b) One hydrogen atom in H2O = +1

c) One oxygen atom in H20 = -2

d) Elemental hydrogen (H) = 0 = zero

e) One aluminum atom in Al(OH)4^-1 = +3

f) One oxygen atom in Al(OH)4^-1 = -2

g) One hydrogen atom in Al(OH)4^-1 = +1

Answer 1

hahaha i just learned this stuff to day. it all checks out.

Answer 2
