Write a word equation for the reaction between potassium and water.

What that guys said bc I toke a test and I toke his answer and I got a 100% just saying hope this helps!!!

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   

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
