28 CO(g) + O2(g) --> 2 CO2(g). What mass of carbon monoxide is needed to produce 120.0mL of carbon dioxide at STP? (Show work)

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   

Ithink carbon dioxide, i am not completely sure.tell me if i am wrong.

Answerstrong acids and bases completely dissociate in water.this is how strong acids and bases are defined. they will ionize 100% in solution, making a non-reversible reaction
