An acid (X) reacts with a base (Y) to produce Mg3(PO4)2. What are X and Y? X = H3PO3; Y = Mg(OH)2 X = H3PO4; Y = Mg(OH)2 X = H3PO4; Y = Ca(OH)2 X = H3PO3; Y = Ca(OH)2 Mark this and return

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   

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
