Which contributes to the polarity of a water molecule? Oa linear shape along with strong covalent bonds

O deflection of hydrogen atoms by lone pairs of electrons

O no difference in the electronegativity of oxygen and hydrogen

deflection of Hydrogen atoms by lone pairs of electrons

explanation:

detials on each model with digrams

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.
