Which of these themes is most closely related to the harlem renaissance

Sauron [17]

.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.

Some scientists believe that life on Earth may have originated near deep-ocean vents. Balance the following reactions, which are

goldenfox [79]

Answer :

(1) The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

(1) The unbalanced chemical reaction is,

$CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the $CH_3SH$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The unbalanced chemical reaction is,

$H_2S(g)+CO(g)\rightarrow CH_3CO_2H(g)+S_8(s)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '8' put before the $H_2S\text{ and }CO$ and the coefficient '4' put before the $CH_3CO_2H$ we get the balanced chemical equation.

The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

A 1500 L weather balloon is at 'a temperature of 290 K on the ground. As it rises the

myrzilka [38]

Answer:

1086.2 L

Explanation:

The computation of the volume of the elevation is given below:

Here we assume the volume of the elevation be x

As we know that

V¹ ÷ T¹ = V² ÷ T²

Here

V^1 = 1500

T^1 = 290

V^2 = x

T^2 = 210

Now place these values to the above formula

So,

1500 ÷ 290 = x ÷ 210

x = 1086.2 L
