Morphology
The meaning is directly compositional: 'sodium hydride' denotes the hydride (a compound with hydrogen) of sodium — i.e. a compound made from sodium and hydrogen (NaH). Though chemical vocabulary is technical, a learner who knows 'sodium' and 'hydride' can infer the compound meaning, so the MWE is transparently built from its constituents.
Etymology
Sodium hydride simply tells you what it is: the metal sodium joined with hydride, a form of hydrogen. Because that form of hydrogen is very reactive, sodium hydride can burn or react with water, and chemists use it as a very strong 'base' to pull hydrogen from other molecules.
