Answer:
The lattice energy of MgS is 4 times larger than that of NaCl
Explanation:
because, MgS has a higher charge that is Mg2+,S2− M g 2 + , S 2 − than NaCl (Na+,Cl−) ( N a + , C l − ) .
Answer=1
Potassium Sulfide= K2S (two metals, one non metal)
Sodium Oxide=Na2O (two metals. one nonmetal)
Sodium Chloride=NaCl (one metal, one nonmetal)
Magnesium Oxide=MgO (one metal, one nonmetal)
Magnesium Chloride=MgCl2 (one metal, two nonmetals)
Answer:
The power must have gone out for that area.
