Iron metal reacts with oxygen to produce iron(iii) oxide. if you have 12.0 moles of iron for complete reaction, you need(can someone explain and show work) .9.0 moles of o2 and produce 6.0 moles of fe2o3.2.9.0 moles of o2 and produce 3.0 moles of fe2o3.3.12.0 moles of o2 and produce 24.0 moles of fe2o3.4.5 moles of o2 and produce 3.0 moles of fe2o3.5.none of the above

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
