Determine the overall reaction and its standard cell potential (in V) at 25°C for the reaction involving the galvanic cell made

mel-nik [20]

Answer:

Standard cell potential is 0.56V

Explanation:

Standard reduction potential ( $E^{0}$ ) are given below-

$E_{Cu^{+}\mid Cu}^{0}=0.52V$

$E_{Fe^{3+}\mid Fe}^{0}=-0.04V$

As $E_{Cu^{+}\mid Cu}^{0}$ is greater than $E_{Fe^{3+}\mid Fe}^{0}$ therefore Fe will be oxidized to $Fe^{3+}$ and $Cu^{+}$ will be reduced to Cu

Oxidation: $Fe(s)-3e^{-}\rightarrow Fe^{3+}(aq.)$

Reduction: $Cu^{+}(aq.)+e^{-}\rightarrow Cu(s)$

------------------------------------------------------------------------------------------------------

Overall: $Fe(s)+3Cu^{+}(aq.)\rightarrow Fe^{3+}(aq.)+3Cu(s)$

Standard cell potential, $E_{cell}^{0}=E_{Cu^{+}\mid Cu}^{0}-E_{Fe^{3+}\mid Fe}^{0}=(0.52+0.04)V=0.56V$

How are waves reflected, absorbed, and transmitted through various materials

EastWind [94]

Answer:

Electromagnetic Radiation

Explanation:

When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. However, because light can travel through space, it cannot be a matter wave, like sound or water waves.

The _______ of a wave is a measure of the amount of energy it carries

Bumek [7]

The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency. Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.
