lana [24]

Gasoline is predominantly octane, C8H18.  Something like soap would be a great homogenizer.  Soap is composed of a long hydrocarbon chain with a tiny, highly polar tip on one end.  Usually, the soap is the anion of a salt, NaX.  This allows the polar end of the soap to stick to water, while the nonpolar end sticks to the oil.

\frac{kg*m*m}{m^3*s*\mu}=1=\frac{kg}{m*s*\mu}

\mu=\frac{kg}{m*s}

A tiger cub has a pattern of stripes on its fur that is similar to that of its parents. Where are the instructions stored that p
madreJ [45]

Answer:

On genes within chromosomes

Explanation:

-The fur pattern is a genetic trait whose instruction is carried in the DNA's base sequence.

-These instructions are organized into genes and each gene is only responsble for the making of a functional product.

-Hence, the instructions are stored on genes within chromosomes.

Identify the following reaction as oxidation and reduction F2(g)+2e-/2F-(aq)​
sertanlavr [38]

Answer:

Reduction

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

In given reaction fluorine gas gain two electron and form fluoride ions.

F₂(g) + 2e⁻    →   2F⁻(aq)

The given reaction is reduction because oxidation state is decreased from zero to -1.

This graph shows two curves pertaining to a hydrogen s orbital.
fgiga [73]

Answer 1) : According to the complete question attached in the answer,

The radial wave function  which is denoted by R_{nl}(r) shown with orange color crosses through zero point. Also, At the the radial nodes, which are spherical shells to some radial distance away from the nucleus there no electron are found.

Also, the radial probability distribution curve denoted as R^{2}_{nl}(r) shown in  blue  color is observed to touch zero, and shows the place of radial node.

Therefore, the total number of nodes will include both the kinds  which has radial and angular nodes which will be represented by <em>'n'</em>.

It is observed that for any atomic orbital, the total number of nodes will be n-1  .


Considering the s orbital of the hydrogen, which has zero angular momentum  (l); (l=0), as it has zero angular nodes.  

Hence, there will be only radial nodes, which is

(n−1  =  total number of radial nodes in s orbitals)

According to the image, there are 4  radial nodes shown, so n  =  5  (as n-1 = 4; therefore, n = 5)

This represents the 5s orbital.


Answer 2) The radial nodes are observed in I'm seeing radial nodes at  

1.9a_{0},  6.4a_{0},13.9a_{0} and  27.0a_{0}.

where  a_{0} represents the  hydorgen bohr atomic radius =  0.0529177 nm


Explanation : It is quite easy to observe the given graph and find out the approximate values of the radial nodes, it does not requires any equation to be solved. Equation can be used to find the radial nodes if it was supplied along with the question. Although by mere speculation one can find out the answer.
