In a closed system, how will a decrease in pressure affect the following reaction: N2O4(g) ⇌ 2NO2(g)?

Answer:

Answer 'A'

Explanation:

In general, if the Σmolar volumes(g) reactants ≠ Σmolar volumes(g) products, a change in atmospheric pressure will shift the reaction equilibrium. If the pressure is increased, the rxn will shift toward the LOWER molar volume side of the rxn or if the pressure is decreased the rxn will shift toward the HIGHER molar volume side. For the reaction N₂O₄(g) ⇄ 2NO₂(g), Vm(N₂O₄(g)) < Vm(NO₂(g)) so, a decrease in atmospheric pressure would shift rxn toward the NO₂(g) side of the equation increasing the moles of NO₂(g). Also, note that if the Σmolar volumes(g) reactants = Σmolar volumes(g) products, no shift in equilibrium will occur regardless of changes in atmospheric pressure.

Which of the following characteristics would make a gas non-ideal?
Marysya12 [62]

Answer:

A. The gas molecules possess kinetic energy.

Explanation:

The characteristics of the Ideal gases are given by the Kinetic Theory of gases which are as follows:-

Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.

Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.

No molecular forces are at work. This means that there is no attraction or repulsion between the particles.

Gas pressure is due to the molecules colliding with the walls

Which is the electron configuration for bromine? 1s22s22p63s23p64s23d104p5 1s22s22p63s23p64s23d104p6 1s22s22p63s23p44s23d104p5 1
Svetach [21]

Answer : The correct option is, 1s^22s^22p^63s^23p^64s^23d^{10}4p^5

Explanation :

The given element bromine belongs to the group 17 and period 4. The symbol of bromine is, Br.

The atomic number of bromine = 35

The total number of electrons present in bromine element = 35

Electronic configuration : It is defined as the arrangement of electrons around the nucleus of an atom.

Hence, the correct electronic configuration of bromine is,

1s^22s^22p^63s^23p^64s^23d^{10}4p^5

Calculate the vapor pressure of a solution made by dissolving 109 grams of glucose (molar mass = 180.2 g/mol in 920.0 ml of wate
Fynjy0 [20]
Given data: <span>molar mass = 180.2 g/mol in 920.0 ml of water at 25 °c.
                   </span><span>the vapor pressure of pure water at 25 °c is 23.76 mm hg. 
</span>Asked: <span>the vapor pressure of a solution made by dissolving 109 grams of glucose
</span><span>
Solution:
moles glucose = 109 g/ 180.2 g/mol=0.605 
mass water = 920 mL x 1 g/mL = 920 g 
moles water = 920 g/ 18.02 g/mol=51.1 
mole fraction water = 51.1 / 51.1 + 0.605 =0.988 
vapor pressure solution = 0.988 x 23.76 = 23.47 mm Hg</span>
