Blast furnaces extract pure iron from the iron(iii) oxide in iron ore in a two step sequence. in the first step, carbon and oxygen react to form carbon monoxide: 2c (s) + o2 (g) → 2co (g)in the second step, iron(iii) oxide and carbon monoxide react to form iron and carbon dioxide: fe2o3 (s) + 3co (g) → 2fe (s) + 3co2 (g)write the net chemical equation for the production of iron from carbon, oxygen and iron(iii) oxide. be sure your equation is balanced.

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
