Asealed container contains 0.10 moles of nitrogen gas and 0.20 moles of oxygen gas. if temperature of the mixture is constant, which of the followimg is true
a molecular masses of 2 gases are the same.
b partial pressures of the two gases are same
c average kinetic energies of the two gases are same.

c. The average kinetic energies of the two gases are the same.  

Step-by-step explanation:

A major postulate of the Kinetic Molecular Theory is that the average kinetic energies of all gases are the same at the same temperature.

a. is wrong. N₂ and O₂ are different elements with different molar masses.

b. is wrong. According to Avogadro's Law, the partial pressure varies directly as the number of moles. There are twice as many molecules of O₂ as of N₂, so p(O₂)  = 2p(N₂).

c) always accurate

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
