Note that the symbol for hydrogen is H so you want to say NaH. At any rate, sodium hydride is a powerful base. Hydrogen gas is given off when NaH deprotonates a molecule so the process is irreversible.
R-H + NaH → R-Na + H2
The principal limitation on NaH is that it is insoluble in ethereal solvents so not as easy to handle as lithium dialkyl amides or organolithiums. Potassium hydride is even more reactive than sodium hydride. Both NaH and KH burst into flames when added to water.

Since I’m guessing this is a gen. chem or HS level question, the “easy” answer are are only a few strong acids (memorize them!), and the rest are weak.
There are seven:
HX (where X is a halogen that is NOT fluorine. ie HCl, HI, HBr.)
Nitric Acid (HNO3)
Sulfuric Acid (H2SO4)
Chloric (HClO3)
Perchloric (HClO4)
Yes there are caveats with that, like chloroacetic acid (mix NaCl and vinegar. Polishes copper quite nicely) is ALMOST a strong acid. And the pH of a dilute strong acid can be higher than a weak acid.
The corresponding question you’re going to ask next is: what are the strong BASES.
They are all M-OH, where M = an alkali metal (column 1), or M(OH)2 where M is an alkali earth metal (really, only Ba, Sr, and (to the extent it dissociates in water, Ca(OH)2 )
