Write the reaction between Hydrochloric acid and Sodium Hydroxide,

and Explain what the endpoint of the reaction is for the reaction and what is important about that point.

The answer is:

CO2 (g) + H2O ( I) > H2CO3 ( aq) H2CO3 ( aq) + NAOH ( aq) > NaCO3 (aq) + H2O ( I)

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
