A blu-ray laser has a wavelength of 405nm. In what region of the electromagnetic spectrum is this radiation? What is its frequen

love history [14]

Answer:

It lies in in the visible region.

Frequency: is 7.407 × 10^-14 Hz

${ \bf{V = f \lambda}} \\ { \tt{3.0 \times {10}^{8} = f \times (405 \times {10}^{ - 9}) }} \\ { \tt{f = 7.407 \times {10}^{14} \: hertz}}$

Explanation:

V is speed of light.

f is frequency

lambda is the wavelength

Calculate the equilibrium constant for the reaction using the balanced chemical equation and the concentrations of the substance

Oliga [24]

Answer:

4.75 is the equilibrium constant for the reaction.

Explanation:

$CO(g)+H_2O(g)\rightleftharpoons CO_2(g)+H_2(g)$

Equilibrium concentration of reactants :

$[CO]=0.0590 M,[H_2O]=0.00600 M$

Equilibrium concentration of products:

$[CO_2]=0.0410 M,[H_2]=0.0410 M$

The expression of an equilibrium constant is given by :

$K_c=\frac{[CO_2][H_2]}{[CO][H_2O]}$

$K_c=\frac{0.0410 M\times 0.0410 M}{0.0590M\times 0.00600 M}$

$K_c=4.75$

4.75 is the equilibrium constant for the reaction.
