Hydrogen (H2)
e.g. Zinc & Hydrochloric Acid
Zn + 2HCl = ZnCl2 + H2
NB
Remember the general acid reaction equations.
Acid +Alkali = Salt + Water
Acid + Base = Salt + Water
Acid + Metal = Salt + Hydrogen
Acid + Carbonate = Salt + Water + Carbon Dioxide.
Hydrogen is made (aka H2)
Carbon dioxide gas is produced when any strong acid is added to a metal carbonate.
Hydrogen gas.

When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
