Hydrogen gas- very explosive when mixed with a spark
Potassium reacts explosively.

When sodium bicarbonate reacts with dilute hydrochloric acid they produce carbon dioxide (CO2)

Hydrogen gas
NiCO3 + HCl =NiCl2 + H2O +CO2
If the acid is hydrochloric acid, then the gas is hydrogen.
Concentrated hydrochloric acid is more reactive than dilute hydrochloric acid. When concentrated hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas more quickly and vigorously compared to when dilute hydrochloric acid reacts with magnesium. This is due to the higher concentration of hydrogen ions in concentrated hydrochloric acid, leading to a faster and more intense reaction.
