Photon energy is proportional to which of the following quantities? speed of light in a vacuum frequency of the light emitting t
charle [14.2K]

Answer:

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.

Explanation:

Energy of the photon is given by expression:

E=h\times \nu=\frac{hc}{\lambda }

E = Energy associated with the photon

\nu  =  frequency of the light

h = Planck's constant =6.626\times 10^{-34} J s

c = speed of the light in vacuum = constant

\lambda =Wavelength of the photon

E\propto \nu

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.

El lago Don Juan, es considerado el más salino de la Tierra, contiene en sus aguas 3.72 mol/kg de cloruro de calcio (CaCl2) y 0.
Alex73 [517]

Answer:

412.8 \frac{gCaCl_2}{kg\ agua} \\\\29 \frac{gNaCl}{kg\ agua}

Explanation:

¡Hola!

En este caso, dado que se nos dieron las moles de cada sal por cada kilogramo de agua, es necesario para nosotros calcular los gramos por medio de la masa molar de estas, que son 110.98 g/mol y 58.44 g/mol respectivamente.

De este modo, realizamos las conversiones de moles a masa como se muestra a continuacion:

3.72\frac{molCaCl_2}{kg\ agua} *\frac{110.98gCaCl_2}{1molCaCl_2}=412.8 \frac{gCaCl_2}{kg\ agua} \\\\0.5\frac{molNaCl}{kg\ agua} *\frac{58.44gNaCl}{1molNaCl}=29 \frac{gNaCl}{kg\ agua}

¡Saludos!
