B. Haber Process
C. Dehydrating copper sulfate (CuSO4)
D. Thermal decomposition of NH4Cl

PLEASE HELP

Answer:

A. Zinc (Zn) reacting with hydrochloric acid (HCl)

Explanation:

The reaction of Zinc with hydrochloric acid is an irreversible chemical process.

What makes a reaction reversible;

  1. it must be involved in reversible chemical processes, no matter how small the extent of the reversibility.
  2. the rate of forward reaction must be equal to the backward one.

So, hydrochloric acid when reacting with Zinc will give a complete chemical change that will go into completion.
