Formation of hydrogen bonds requires hydrogen atoms and what else? view available hint(s) formation of hydrogen bonds requires hydrogen atoms and what else? water polar covalent bonds oxygen ionic bonds?

H must pair with Fluorine, Oxygen, or Nitrogen

Explanation:

water has polar covalent bonds, the intermolecular forces are hydrogen bonds, London and Dipole forces

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
