Achemistry student needs 90.00 g of 2-ethyltoluene for an experiment. he has 0.20kg available of a 21.7% w/w solution of 2-ethyltoluene in carbon tetrachloride.

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.

imma come back to you hold on

the answer is definitely c.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
