How do nebulae and other interstellar media propagate creation of building block molecules like H2O, etc?

[Anonymous No.1910980]

From what I understood particles in space are somehow drawn to eachother hence the existence of nebulae.

This creates pressure, possibly allowing the creation of H2O.

Could be completely wrong tho

Star-forming nebulae start as clouds of hydrogen which eventually condense and compact enough initiate nuclear fusion - which initially creates Helium but later in the star's life cycle also creates heavier elements (up to and including iron, in theory). Heavier elements are though to be created by the power of large stars exploding in supernovae.

In water, Hydrogen is incredibly common. Oxygen is rarer, but often combines with hydrogen due to hydrogen's high electronegativity (meaning that the three molecules bond together to form a robust, polarised molecule - you can see this in action if you comb your hair then hold the comb near a thin stream of tapwater; the water is deflected by the static electric field).

tl;dr: nuclear fusion.

So basically just as I thought, the pressure allows for chemical reactions.

Figured the creation of water had to part of the creation of a star which generally happens in supermassive nebulae, togheter with all the other elements.
