what mass of copper 2 oxide will just neutralise dilute nitric 6 acid containing 3.15 of pure nitric 5 dissolved in water​

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.

the answer would be c

the product of the pressure and volume is also constant
