It has been proposed that North America is moving west at about 2 cm per year. How many kilometers would it move in 5,000 years?
m_a_m_a [10]

Answer:

0.1 kilometer

Explanation:

First, multiply 5,000 by two to get your cm after 5,000 years which is 10,000 cm and then divide by 100,000 to convert to kilometers which is 0.1.

The value of delta for the [C_rF_6]^3- complex is 182 kJ/mol. Calculate the expected wavelength of the absorption corresponding
kirza4 [7]

Answer:  Yes the absorb in the visible range.

Explanation:

The relationship between wavelength and energy of the wave follows the equation:

E=\frac{Nhc}{\lambda}

where,

E = energy of the wave  = 182 kJ/mol  = 182000 J/mol

N = avogadro's number =  6.023\times 10^{23}

h = plank constant = 6.6\times 10^{-34}Js^{-1}

c = speed of light = 3\times 10^8m/s

\lambda = wavelength of the wave = ?

Putting all the values:

182000=\frac{6.023\times 10^{23}\times 6.6\times 10^{-34}\times 3\times 10^8m/s}{\lambda}

\lambda=0.65\times 10^{-6}m=650nm    (1nm=10^{-9}m)

The wavelength range for visible rays is 400 nm to 750 nm, thus the complex absorb in the visible range.
