Ответ:
The formula equation that shows a reversible reaction is
NH4Cl (s) ⇔ NH3 (g) + HCl (g) ( answer C)
Explanation
Reversible reaction is a chemical reaction where the reactants form products , where in turn react together to form reactant back. The reaction of NH4Cl (s)⇔ NH3(g) + HCl (g) is a reversible reaction since NH4Cl decompose to form NH3 and HCl which in turn react together to form NH4Cl back .Ответ:
Its c I just took the test
