Calculate the number of moles of NH3(g) produced when 0.150 mol N2 is allowed to react with 0.430 mol H2(g). N2(g) + 3 H2(g) → 2 NH3(g)

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
