Calculate the volume of carbon dioxide produced when 250 g of pentane, C3H12, burn. Assume the carbon dioxide is cooled to STP.

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.

if you're asking what comes out, it's steam.

what is the question here. i think you messed up.
