How many atoms in the pictured molecule can form hydrogen bonds with water molecules?

Explanation:

Please, find the  image with the pictured molecule for this question attached.

The molecule has one oxygen atom (red) covalently bonded to one hydrogen atom (light grey), one nitrogen atom (blue) covalently bonded to two hydrogen atoms (light grey), and two carbon atoms (dark grey) bonded each to two hydrogen atoms (light grey).

Hydrogen bondings are intermolecular bonds (bonds between atoms of two different molecules not between atoms of the same molecule). The hydrogen bonds are attractions between the positive end of one hydrogen atom and the negative end of a small atom of other molecule (N, O, or F).

Since, nitrogen and oxygen are much more electronegative than hydrogen atoms, you conclude that:

So, those are three ends of the molecule that can form hydrogen bonds with water molecules.

The hydrogen bondings are only possible when hydrogen is covalently bonded to N, O or F atoms.

- decrease the number of plants and animals living in the water.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
