Question

On January 1, 2012, the ledger of Kindt Com pony contained the ability accounts.During January, the company's employees earned wages of >>74,560. Withholdings related to these wages were $5,689 for Social Security (FICA). 5S.311 for federal Income tax, ard $1,593 for state income tax. The company owed no money related to these earrnngs for federal or state unemployment tax. Assume that wag; earned during January will be paid during February No entry had been recorded for wages of payroll tax expense as of January 31.

Explanation / Answer

a) If we want to find the energy associated with a change in quantum number of a hydrogen atom, you need this equation:

E= -RH (1/n2f - 1/n2i)    Where  RH is a constant = 2.179 x 10-18

So, we can calculate :

E = - 2.179 x 10-18 (1/22 - 1/52) = -4.58 x 10-19 J Energy was liberated. (E<0)

b) To calculate waveleght you have:

1/ = R(1/n2f - 1/n2i)   where R = Rydberg coonstant = 1.097 x 107 m-1

1/ = 1.097 x 107 m-1 (1/22 - 1/52) =2.3037 x 106m-1

= 1/2.3037 x 106m-1 = 4.34 x 10-7 m = 4.34 x 10-7 m x 109 nm/m = 434 nm
