An unknown solid did not melt by 160 degree Celsius and did not dissolve in water....
Homework Answers
Ionic compounds generally dissolves in water and dissociates into ions brcause of polarity. for example NaCl dissolves in water and gives Na+ and Cl- ions.
Nonpolar covalent compounds does not dissolve in water like oil and benzene.
So answer is it is an covalent nonpolar compound.

Only about 0.16mg of AgBr(s) will dissolve in 1.0L of water (this volume of solid is smaller than the head of a pin). In a solution of ammonia that contains 0.10 mol ammonia per liter of water, there are about 555 water molecules for every molecule of ammonia. However, more than 400 times as much AgBr (68mg) will dissolve in this solution as in plain water. Explain how such a tiny change in the composition of the solution can have...
