An aqueous solution containing 6.37 g of an optically-pure compound was diluted to 4.00Ã102 mL with water and placed in a 10.0 cm long polarimeter tube. The measured rotation was â2.07° at 25° C. Calculate the specific rotation of the compound.

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.

have a great day because if you dont you and i will be sad

it is a solid
