1-

A high altitude balloon is filled with 1,410 L of hydrogen at a temperature of 21°C and a pressure of 745 torr. What is the volume of the balloon at a height of 20 km, where the temperature is -48°C and the pressure is 63.1 torr?


2- What is the root mean square speed of a F2 molecule at 50°C?


3- Given the following gas molecules at 30°C, which would be expected to have the slowest average speed?

H2O       SF4     H2     N2O     


4- The Rydberg formula can also be written as:

Δ E = k ( 1/ n^1/2 − 1/ n^2/2 )


 where the constant  k = 2.178 × 10^ − 18 J


Solve when a single hydrogen atom absorbs 2.09 x 10^-18 J with its electron starting at the first energy level, at what energy level does the electron end? Remember n = whole intergers


5- Green light has a wavelength of 499 nm. What is the frequency?


6- What is the maximum number of orbitals which have quantum numbers:        n = 4   and     l = 1


7- Which of the following sets of quantum numbers are not allowed for an electron in an atom?

 

Choice n l ml ms


A 2 1 0 +1/2


B 2 3 +1 -1/2


C 3 2 -2 -1/2


D 2 2 0 +1/2


E 2 1 0 +1/2


8- List the following ions in order of increasing radius:

Br-, Li+, Te2-, Mg2+
