Answer 1

Q1)

2K3PO4(aq) + 3MgCl2(aq) -------------> Mg3(PO4)2 (s) + 6 KCl(aq)

Q2)

NaCl (aq) + CuSO4(aq) -------------> No reaction

As neither CuCL2 nor Na2SO4 are insoluble. All ions remain in solution.

Q3)

Na+ is an ion ,CH3CH2Cl is a polar molecule.Thus ion-dipole ionteractions are present.

H2O and CH3CH2OH , both are polar and are capable of forming H - bonds.
so the interactions are HYDROGEN BONDING

Mg+2 ion and Br- is ion. So ELECTROSTATIC ATTRACIONS.

CH3CH2Oh is polar with H - bonding. SO4-2 is an ion .
Thus ion-dipole interations
Be+2 and H2O ion-dipole interactions.

SO4-2 and H2O ion-dipole interactions
