6. Calculate the wavelength for the transition from n = 4 to n = 2, and state the name geven to the spectroscopic series to which this transition belongs?​

C: plants and animals

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   

The answer would be true

Answer: temperature? i hope this and have a wonderful
