Combustion of a 3.59 g sample of a compound containing only carbon, hydrogen, and oxygen produced 5.26 g of CO2 and 2.15 g of H2O. What is the empirical formula of the compound?

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   

What record? the question is incomplete

Answer; carbon monoxide (co);
