2FeCl3 ---> 2FeCl2 + Cl2

2 answers:

8 0

The correct options are as follows:
1. In the chemical equation given above, Fe3+ IS REDUCED.
A reduction is a process in which an atom of an element gains an electron and therefore become reduced. In this type of reaction, the positive character of the atom is reduced. Looking at the equation given above, you will notice that, the positive character of Iron is reduced form +3 to +2.

2. In the reaction given above, the chlorine atom is OXIDIZED.
An oxidation is a process in which an atom loses an electron, thereby increasing its oxidation number. In this case, the positive character of the atom is increased. Looking at the chlorine atom given above, you will notice that it has a charge of -1 before and now it has change to neutral, which means that, it has given out the electron it gains earlier.

3. This type of redox reaction can not take place. This is because, in chemical reaction, the chlorine atom is always looking for another element that will donate an electron to it in order to become stable. Thus, chlorine atom easily gain electrons but it can not donate an electron to another element.<span />

What would be the wavelength of light that has a frequency of 3 X<br> 10-4 Hz in a vacuum?

ziro4ka [17]

Answer:

$\lambda=10^{12}\ m$

Explanation:

Given that,

The frequency of the light, $f=3\times 10^{-4}\ Hz$

We need to find the wavelength of the light.

The relation between frequency, wavelength and the speed of light is given by :

$c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3\times 10^{-4}}\\\\\lambda=10^{12}\ m$

So, the wavelength of the light is $10^{12}\ m$ .

Describe Newton's Law of Viscosity and the constitutive behavior of non-Newtonian fluid

CaHeK987 [17]

Answer:

- "Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers".

- A non-Newtonian fluid is a fluid which the relationship between the shear stress and the velocity gradient is not properly defined by the Newton's viscosity law, thus, the behavior is not lineal but potential.

Explanation:

Hello, here the answers:

- "Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers" (taken from Kundu, P. K., Cohen, I. M., & Dowling, D. R. (2012). Fluid mechanics.), thus, it means that when you have a fluid with an acting-on-it share stress (an external force which move the fluid), the related velocity gradient (variation or change in velocity) at which the layers are moving are related as:

$\pi =-v \frac{du}{dy}$

Whereas $\pi$ is the shear stress, $v$ is the viscosity and the differential accounts for the change in the velocity in the arbitrary $y$ coordinate.

$\pi =-v (\frac{du}{dy})^n$

Whereas $n$ accounts for a decreasing or increasing behavior of the shear stress.

Best regards.
