Solution: One of relatively few reactions that takes place directly between two solids at room temperature isBa(OH)2 • 8 H 2O (s) + NH 4SCN (s) → Ba(SCN) 2 (s) + H 2O (l) + NH 3 (g)In this equation, the • 8 H 2

Problem

One of relatively few reactions that takes place directly between two solids at room temperature is

Ba(OH)2 • 8 H 2O (s) + NH 4SCN (s) → Ba(SCN) 2 (s) + H 2O (l) + NH 3 (g)

In this equation, the • 8 H 2O in Ba(OH) 2 • 8 H2O indicates the presence of eight water molecules. This compound is called barium hydroxide octahydrate. Balance the equation.
