Avessel contained n2, ar, he, and ne. the total pressure in the vessel was 987 torr. the partial pressures of nitrogen, argon, and helium were 44.0, 486, and 218 torr, respectively. the partial pressure of neon in the vessel was torr. a) 42.4 b) 521 c) 19.4 d) 239 e) 760

The correct answer is option d.

Explanation:

Total pressure of gasses in container = p = 987 Torr

Partial pressure of the nitrogen gas =

Partial pressure of the argon gas =

Partial pressure of the helium gas =

Partial pressure of the neon gas =

According to Dalton's law of partial pressure: Total pressure is equal to sum of partial pressure of all the gases present in the mixtures.

x = 239 Torr

The partial pressure of neon in the vessel was 239 Torr.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
