8.89. Earth's Crust The following chemical reactions have helped to shape Earth's crust. Determine the oxidation numbers of
all the elements in the reactants and products, and identify
which elements are oxidized and which are reduced:
2. 3 SiO2(3) + 2 Fe:0,(3) →3 Fe SiO.(s) + O2(g)
t. SiO2(3) + 2 Fe(s) + O2(g) → Fe SiO (5)
c4 FeO(s) + O2(5) + 6 HOO4 Fe(OH)3(s)
