If 0.7 moles of potassium chloride are dissolved in 0.5 l of water, what is the concentration of the solution? 1.4 m 0.7 m 0.5 m 0.35 m

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   

Nonmetal are moldable and easily shaped

I'm sorry but i'm only grade

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
