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.

Vaselesa [24]

Answer:

%age Yield = 22.72 %

Explanation:

The balance chemical equation is as follow;

2 NH₄Cl + CaO → 2 NH₃ + CaCl₂ + H₂O

Step 1: Calculate Moles of CaO, NH₄Cl and NH₃;

CaO:

Moles = Mass / M.Mass

Moles = 112 g / 56.07 g/mol

Moles = 1.99 moles of CaO

NH₄Cl:

Moles = Mass / M.Mass

Moles = 224 g / 53.49 g/mol

Moles = 4.18 moles of NH₄Cl

NH₃:

Moles = Mass / M.Mass

Moles = 16.3 g / 17.03 g/mol

Moles = 0.95 moles of NH₃

Step 2: Calculate Limiting reagent as:

According to equation.

2 moles of NH₄Cl reacts with = 1 mole of CaO

So,

4.18 moles of NH₄Cl will react with = X moles of CaO

Solving for X,

X = 4.18 mol × 1 mol / 2 mol

X = 2.09 mol of CaO

This means that none of the given reagent is limiting reagent. They both are almost equal in number of moles.

Step 3: Calculate Theoretical Yield of NH₃ as;

According to equation.

2 moles of NH₄Cl produced = 2 moles of NH₃

So,

4.18 moles of NH₄Cl will produce = X moles of NH₃

Solving for X,

X = 4.18 mol × 2 mol / 2 mol

X = 4.18 mol of NH₃

Step 4: Calculate Percentage Yield as;

%age Yield = Actual Yield / Theoretical Yield × 100

%age Yield = 0.95 mol / 4.18 × 100

%age Yield = 22.72 %

Why does salt dissolve in water?

tigry1 [53]

The water dissolves the salt because the water molecules are able to interact with the salt-forming particles, called ions. When the water Interacts with the trainers of the salt ions, the solid salt crystal structure Suffers breakdown, until the trainers of the salt ions are completely surrounded by water molecules. At this time the salt is fully dissolved by water.

hope this helps!
