Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams
<h3>Stoichiometric calculation</h3>
From the equation of the reaction:
N + O ---------> NO
Mole ratio of N to NO is 1:1
Mole of 25.0 g of NO = 25/30.01 = 0.833 moles
Equivalent mole of N = 0.833 moles
Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

Answer:
Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer.
Heat energy is required.
In distillation, the solution is first heated, where heat energy is required, such as using a bunsen burner.
When the solution is heated, the water may reach its boiling point and evaporate. However, salt does not. When water molecules evaporates, it travels through a condenser that cools it down into liquid again. Therefore we get pure water. Salt is also obtained in the original beaker.
Therefore to first start this process, heat energy is required.
Sublimation occurs more readily when definite weather circumstances are present such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes where the air pressure is less than at lower altitudes and energy such as strong sunlight is also needed. Sublimation happens a lot in the south face of Mt. Everest which have low temperatures, strong winds, intense sunlight, very low air pressure and the recipe for sublimation to occur.
The best way (in my opinion) is to put it in a table or spreadsheet.
