Hydrogen gas produced by

alkali metals combined with H, will produce H2 as one product

Hydrogen sulfide is always a

gas

sulfur dioxide (SO2) gas produced by

H2SO3 (sulfurous acid) -> SO2(g) + H2O(l)

carbon dioxide (CO2) gas produced by

H2CO3 (carbonic acid) -> CO2(g) + H2O(l)

ammonia gas (NH3) produced by

NH4OH (ammonium hydroxide) -> NH3(g) + H2O(l)

water produced by

metal oxide (base) neutralizing an acid, or non-metal oxide (acid) neutralizing a base

All compounds of alkali metals in group 1A and NH4 are

Soluble
