For the reaction Fe2O3 + 3CO --> 2Fe + 3CO2, how many grams of carbon dioxide are produced when 10.0 grams of iron(III) oxide are reacted?

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
