Respuesta :
Ammonia, or NH3, has a vaporization heat of 23.4 kJ/mol. 915.g of ammonia condenses at 33.5°C, resulting in a 53.832 mol change in entropy, or S.
ΔHvap = 23.4KJ/mol
Mass of NH3 = -915g
T = -33.5° = 239.5k
moles = mass/molar mass = 915 / 17 g/mol
moles = 53.832 mol
Nitrogen and hydrogen combine to generate the inorganic substance ammonia, which has the formula NH3. Ammonia is an odorless gas with a strong unpleasant odor. It is a stable binary hydride and the simplest pnictogen hydride. In terms of biology, it is a typical nitrogenous waste, especially for aquatic animals, and it considerably contributes to the dietary requirements of terrestrial creatures by acting as a precursor to 45% of the world's food and fertilizers[12]. The production of fertilizers [13] in a variety of shapes and compositions, including urea and diammonium phosphate, uses around 70% of ammonia. Also sprayed straight to the soil is ammonia in its purest form.
