Answer to Question #333205 in General Chemistry for jeff

Question

Determine all possible ratios for the following balanced chemical equations.

a) 4Al(s) + 3O2(g)→2Al2O3(s)

b) 3Fe(s) + 4H2O(l) → Fe3O4(s) + 4H2(g)

Answer 1

а) Al:O₂ = 4:3

Al:Al₂O₃ = 2:1

O₂:Al₂O₃ = 3:2

б) Fe:H₂O = 3:4

Fe:Fe₃O₄ = 3:1

Fe:H₂ = 3:4

H₂O:Fe₃O₄ = 4:1

H₂O:H₂ = 1:1

Fe₃O₄:H₂ = 1:4
