In Act IV, Scene 1, of A Midsummer Night's Dream, as the drama nears resolution, to whom does Demetrius address these lines?My love to Hermia,
Melted as the snow, seems to me now
As the remembrance of an idle gaud

Taking into account the definition of molarity, you would measure out 72.732 g of K₂SO₄ to prepare 550 ml of a 0.76 M solution.

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity is expressed in units.

Mass of K₂SO₄

In this case, you prepare 550 ml of a 0.76 M solution​. This is, you know:

• Molarity= 0.76 M
• number of moles= ?
• volume= 550 mL= 0.550 L

Replacing in the definition of molarity:

Solving:

number of moles= 0.76 M × 0.550 L

number of moles= 0.418 moles

Being the molar mass of K₂SO₄ 174 , that is, the amount of mass that the compound contains in one mole, the mass contained in 0.418 moles is calculated as:

0.418 moles×174 = 72.732 g

Finally, you would measure out 72.732 g of K₂SO₄ to prepare 550 ml of a 0.76 M solution.

Answer:

Explanation:

Hello,

In this case, by considering that the both the volume of the solution of potassium sulfate and its concentration are given, one solves for the required mass considering the following proportional factors related stoichiometrically:

Best regards.

Answer:

3.6*105g CH4

Explanation:

The detailed solution is shown on the image. From the detailed chemical reaction, we calculate the mass of methane required in the standard combustion reaction of methane and use it to estimate the mass required to produce the quantity of heat required in the question.

Final answer:

To supply the energy needed for an average home in Colorado, approximately 3.58 x 10^8 grams of natural gas (methane) must be burned.

Explanation:

To calculate the amount of natural gas (methane) required to supply the energy needed for an average home in Colorado, we can use the balanced chemical equation for the combustion of methane:

CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)

The molar enthalpy change for this reaction (ΔH°rxn) is -890.4 kJ/mol. First, we need to convert the energy requirement from kilojoules to joules:

2.00 x 107 kJ = 2.00 x 1010 J

Next, we can use the molar enthalpy change to calculate the number of moles of methane required:

moles of CH4 = energy requirement / mlar enthalpy change

moles of CH4 = 2.00 x 1010 J / (-890.4 kJ/mol)

Finally, we can convert the number of moles of methane to grams using the molar mass of methane:

molar mass of CH4 = 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol

grams of CH4 = moles of CH4 * molar mass of CH4

Therefore, the number of grams of natural gas (methane) that must be burned to supply this energy is approximately:

grams of CH4 = (2.00 x 1010 J / (-890.4 kJ/mol)) * 16.04 g/mol

Simplifying the calculation:

grams of CH4 ≈ 3.58 x 108 g

The answer is:

Sublimation

The explanation:

The most state has the high volume is the gas state.

So here the answer is between vaporization and sublimation???

and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas

and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°

here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.

Answer: The correct answer is Option 4.

Explanation:

All these processes are the physical processes which occurs between the phases of matter.

Solid state is the phase where particles are closely arranged and the volume of this state is less.

Liquid state is the phase where particles are not closely arranged and the volume of this state is more than solid but less than gaseous state.

Gaseous state is the phase where particles are loosely arranged and this state has the largest volume.

• Deposition is the physical process in which gaseous state is converted to solid state. The volume of the substance decreases.

• Melting is the the physical process in which solid state is converted to liquid state. The volume of the substance increases.

• Vaporization is the physical process in which liquid state is converted to gaseous state. The volume of the substance increases.

• Sublimation is a physical process in which solid states is converted to gaseous state. The volume of the substance increases and in this case, the increment in volume is the maximum.

Hence, the correct answer is Option 4.

Answer:

The correct answer is option (3) "using nonviolent tactics such as boycotts and hunger strikes".

Explanation:

Cesar Chavez was a leader of American labor and civil right activists that fought to unionized migrant farm workers by the creation of The National Farm Workers Association. Cesar Chaves used nonviolent tactics to support the migrant farm workers. For instance, when Filipino American farm workers protested for higher wages in 1965, he encouraged Americans to boycott table grapes to support them; while he once performed a 24-day hunger strike in 1972 in the Santa Rita Center as a response to Arizona prohibiting boycotts and strikes by farm workers.

Answer:

one more proton

Explanation:

The symbol for phosphorous is P; it is element 15 on the Periodic Table. That

means phosphorous-31 has 15 protons. The symbol for sulfur is S; it is

element 16 on the Periodic Table. Sulfur-32 has 16 protons.
