How do we know that IBr is polar and CO2 is non polar?

Calculate AH for the following reaction, FeO(s) + CO(g) -----> Fe(s) + CO2(g), from the following data, Fe2O3(s) + 3CO(g) -----> 2Fe(s) + 3CO2(g) 3Fe2O3(s) + CO(g) > 2FE3O4(s) + CO2(g) Fe;O4(s) + CO(g) AH = -23 KJ AH = -39 KJ --- -- -----> 3FeO(s) + CO2(g) AH =+18 KJ %3D

4. LaCoO3 is a very unusual magnetic material that exhibits different types of magnetism in different temperature ranges. It has been shown to be (a) paramagnetic, (b) ferromagnetic, and (c) diamagnetic depending on the temperature. Sketch the M vs. H behavior that would be expected for each below. Be sure to label your axes. (a) (b) (c)
