Question

Filll in with an answer from the following:

1) Assuming you have constant pressure and number moles, if you fill up a balloon with a certain volume of a gas at 445 K, when the volume is doubled, the temperature will _______________ (a)decrease by a factor 3

(b)increase by a factor of 4

(c)decrease by a factor of 2

(d)increase by a factor of 3

(e)increase by a factor of 2.

2) Which statement is true for the decomposition of 2NH3 (l)  ⟶ N2 (g) + 3H2 (g) ___________ (Δ?&Δ? ?????ℎ?????). 

(a)Δ? is less than Δ? because of the pressure-volume work done by the gaseous products.

(b)Δ? is greater than Δ? because the pressure is constant.

(c)Δ? is greater than Δ? because of the pressure-volume work done by the gaseous products.

(d)Δ? is less than Δ? because the atmosphere does pressure-volume work done by the gaseous products.

(e)Δ? is equal Δ? because both are state functions. 

3)Consider the following energy-level diagram for a particular electron in an atom         The following statement is incorrect: ________________.

(a) they are all incorrect.

(b) We would observe an electronjumping from level 2 to level 1 as a single line in a line spectrum.

(c) If the electron is in level 2, it may jump to level 1 by emmitting a photon with energy of |Δ?|.

(d) If the electron is in level 1, it may jump to level 2 by absorbing any photon having energy of at least |Δ?|.

(e) If the electron is in level 1, it may jump to level 2 by absorbing a photon with energy of |Δ?|.

 4) The following configuration, [Ne]3s13p1, may represent                 _____________. 

(a) an excited-state electron configuration of a Mg atom.

(b) a ground-state electron configuration of a Mg+ atom.

(c) a ground-state electron configuration of a Al+ atom.

(d) a ground-state electron configuration of a Na+ atom.

(e) an excited-state electron configuration of a Ne- anion.
