Question

The equation of hydrogen preparation(2 markas)​

Answer 1

Answer:

The chemical reactions that take place during the preparation of hydrogen gas via this method are listed below.

General Format: Metal + Dilute Acid → Salt of Metal & Acid + Hydrogen

With Hydrochloric Acid: Zn + 2HCl → ZnCl2 + H2

With Sulphuric Acid: Zn + H2SO4 → ZnSO4 + H2

Finally, the hydrogen gas can be collected by the downward displacement of water.
