.The most common theme found in the Harlem Renaissance art was that of presenting a well educated, sophisticated African-American.

Explanation:

Additionally, the Harlem Renaissance was viewed primarily as a literary movement targeted in Harlem and growing out of the black migration and therefore the emergence of Harlem because of the premier black metropolis within u. s. Music and theatre were mentioned in brief, a lot of as background and native colour, as providing innovation for poetry and local colour for fiction Harlem Renaissance, an efflorescence of African yank culture, significantly within the inventive arts, and therefore the most powerful movement in African yank literary history. some common themes were: alienation, position, use of people material, use of the Blues tradition.

An oxide of phosphorus contains 56.4% phosphorus and 43.6% oxygen. It's relative molecular mass is 220. Find both the empirical

sladkih [1.3K]

Moles of P = 56,4g/30,974g/mole = 1,82 moles P
moles of O = 43,6/15,999 = 2,73 moles of O

converting to the simplest ratio:
For P : 1,82/1,82 = 1
For O : 2,73/1,82 = 1,5

1 P and 2 oxygens.
PO2 -> the empirical formula

If NaOH is added to 0.010 M Al3+, which will be the predominant species at equilibrium: Al(OH)3 or Al(OH)- 4 ? The pH of the sol

fredd [130]

Answer:

Al(OH)- 4,

Explanation:

NaOH added to 0.010 M Al3+

The predominant species at equilibrium will be = Al(OH)- 4, and this because sodium hydroxide ( NaOH ) is a base will readily form a stable complex ion with aluminum ion like ( Al( OH ) - 4 . also the higher the Kf value the more stable the complex ion becomes and the more soluble Al(OH)3 becomes

hence the predominant species at equilibrium is : Al(OH)- 4,

Consider a transition of the electron in the hydrogen atom from n=3 to n=7.

kow [346]

Answer:

For a: The wavelength of light is $1.005\times 10^{-6}m$

For b: The light is getting absorbed

Explanation:

For a:

To calculate the wavelength of light, we use Rydberg's Equation:

$\frac{1}{\lambda}=R_H\left(\frac{1}{n_i^2}-\frac{1}{n_f^2} \right )$

Where,

$\lambda$ = Wavelength of radiation

$R_H$ = Rydberg's Constant = $1.097\times 10^7m^{-1}$

$n_f$ = Higher energy level = 7

$n_i$ = Lower energy level = 3

Putting the values in above equation, we get:

$\frac{1}{\lambda }=1.097\times 10^7m^{-1}\left(\frac{1}{3^2}-\frac{1}{7^2} \right )\\\\\lambda =1.005\times 10^{-6}m$

Hence, the wavelength of light is $1.005\times 10^{-6}m$

For b:

There are two ways in which electrons can transition between energy levels:

Absorption spectra: This type of spectra is seen when an electron jumps from lower energy level to higher energy level. In this process, energy is absorbed.
Emission spectra: This type of spectra is seen when an electron jumps from higher energy level to lower energy level. In this process, energy is released in the form of photons.

As, the electron jumps from lower energy level to higher energy level. The wavelength is getting absorbed.

Which two factors are essential for a molecule to be considered polar? nonpolar bonds and asymmetrical structure, nonpolar bonds

timama [110]

A nonpolar molecule is entirely symmetric. For a molecule to be nonpolar, it must have at least a linear, trigonal planar, or a tetrahedra shape. However, that’s not totally enough. For the molecule to be completely symmetric, aside from having a symmetric shape, all of the atoms that are connected to the central atom must be alike. Therefore, symmetry has two components, they are the geometric arrangement of the outer atoms and whether or not they are all the same.

Fundamentally, non-uniform or it is the uniform, distribution of electrons that ascertains if a molecule is polar or nonpolar, but this distribution is established by the dispersal and distinctiveness of the atoms in a molecule.
