One of relatively few reactions that takes place directly between two sollds at room temperature is Ba(OH), · 8H2O(8) + NH4 SCN(8) → Ba(SCN), (8) + H2O(1) + NH3 (9) In this equation, the 8H2O in Ba(OH), · 8H2O indicates the presence of eight water molecules. This compound is called barium hydroxide octahydrate. a. Balance the equation. (Use the lowest possible coefficients for the reaction.)

Question

Transcribed Image Text:One of relatively few reactions that takes place directly between two solids at room temperature is
Ba(OH), · 8H20(s) + NH4 SCN(s)
Ba(SCN),(8) + H2O(1) + NH3 (9)
In this equation, the 8H2O in Ba(OH), · 8H2O indicates the presence of eight water molecules. This compound is called barium hydroxide octahydrate.
a. Balance the equation.
(Use the lowest possible coefficients for the reaction.)
NH4 SCN(s)
Ba(OH), · 8H2O(s) +
Ba(SCN), (s) +
H20(1) +
NH3 (g)
b. What mass of ammonium thiocyanate (NH4 SCN) must be used if it is to react completely with 5.0 g barium hydroxide octahydrate?
Mass =
