Question 18

The thermal decomposition of ammonium chloride is represented by the following equation:

NH4Cl(s)⇌NH3(g)+HCl(g) \text{NH}_4\text{Cl(s)} \rightleftharpoons \text{NH}_3\text{(g)} + \text{HCl(g)} NH4​Cl(s)⇌NH3​(g)+HCl(g)

State what the symbol ⇌ \rightleftharpoons\,⇌ represents in this equation.
