The balanced reaction equations are given below. They are all examples of double displacement.

a) balanced reaction equation of the reaction between aqueous copper(II) nitrate and aqueous potassium hydroxide, resulting in the formation of solid copper(II) hydroxide and aqueous potassium nitrate

$Cu(NO_{3} )_{2}(aq)+2KOH(aq)$ → $Cu(OH)_{2} (s) + 2KNO_{3}(aq)$

b) balanced reaction equation of the double displacement between gaseous boron cyanide and liquid water resulting in the formation of solid boric acid and gaseous hydrogen cyanide

$2B(CN)_{3} (g) + 6H_{2} O$ → $2H_{3} BO_{3} (s)+6HCN(g)$

c) balanced reaction equation between solid calcium silicate and gaseous hydrogen fluoride resulting in the formation of gaseous silicon fluoride, solid calcium fluoride and liquid water

$CaSiO_{3}(s) + 6HF (g)$ → $SiF_{4}(g)+CaF_{2}(s)+3H_{2}O(l)$
