Derive the units for specific heat from the equation q = mcΔT. Use units of joules (J) for heat, grams (g) for mass, and degrees Celsius (°C) for temperature.

Ions gain or lose electrons

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
