Use the thermochemical equations shown below to determine the enthalpy for the final reaction:

2Fe(s) + 3⁄2O2(g) ---> Fe2O3(s) ΔH = kJ

Any photo? or something

Idk the answer sorry

Ithink it’s one of those things that you put the object on

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
