1. The value of A is 3 atm

2. The value of B is 9.99976 KPa

3. The value of C is 0.0092 atm

4. The value of D is 7 mmHg

<h3>Conversion scale </h3>
  • 1 atm = 101.325 KPa
  • 1 atm = 760 mmHg

<h3>1. How to determine A</h3>

101.325 KPa = 1 atm

Therefore,

303.98 KPa = 303.98 / 101.325

303.98 KPa = 3 atm

Therefore, the value of A is 3 atm

<h3>2. How to determine B</h3>

760 mmHg = 101.325 KPa

Therefore,

75 mmHg = (75 × 101.325) / 760

75 mmHg = 9.99976 KPa

Thus, the value of B is 9.99976 KPa

<h3>3. How to determine C</h3>

101.325 KPa = 1 atm

Therefore,

0.9333 KPa = 0.9333 / 101.325

0.9333 KPa = 0.0092 atm

Thus, the value of C is 0.0092 atm

<h3>4. How to determine D</h3>

101.325 KPa = 760 mmHg

Therefore,

0.9333 KPa = (0.9333 × 760) / 101.325

0.9333 KPa = 7 mmHg

Thus, the value of D is 7 mmHg

If you start with 0.30 m mn2 , at what ph will the free mn2 concentration be equal to 4.6 x 10-11 m?
aksik [14]

If you start with 0.30 m Mn₂ , at 12.5 pH, free Mn₂ concentration be equal to 4.6 x 10⁻¹¹ m

Initial molarity of Mn₂ = 0.30 M

Final molarity of Mn₂ = 4.6 x 10⁻¹¹

pH = ?

Ksp [Mn(OH)₂] = 4.6 x 10⁻¹⁴ (standard value)

Write the ionic equation

    Mn(OH)₂   →    Mn⁺² + 2OH⁻

    [Mn⁺²] = 4.6 x 10⁻¹¹

We will calculate the concentration of OH⁻ by using Ksp expression

    Ksp = [Mn⁺²][OH-]²

    [Mn⁺²][OH⁻]² = 4.6 x 10⁻¹⁴

    [OH⁻]² = 4.6 x 10⁻¹⁴ / 4.6 x 10⁻¹¹

    [OH⁻]² = 10⁻³

    [OH⁻] = (10⁻³)¹⁽²

    [OH⁻] = 0.0316 M

Calculate the pOH

    pOH = -log [OH⁻]

    pOH =  -log [0.0316]

    pOH = 1.5

Now calculate pH

   pH = 14 - pOH

   pH = 14 - 1.5

   pH = 12.5

What happens as a result of the kinetic energy of the particles in a liquid being comparable with the intermolecular attractions
sdas [7]

Answer : Option D) The particles move enough that they are not fixed in place, and the liquid can flow.

Explanation : The kinetic energy of the particles are allowed to move freely and are in motion when in the liquid state whereas the intermolecular particles can just flow; as the intermolecular attractions between the particles allows the liquid to flow by giving them a force to flow.

A sample of He gas (3.0 L) at 5.6 atm and 25°C was combined with 4.5 L of Ne gas at 3.6 atm and 25°C at constant temperature in
In-s [12.5K]

Answer:

3.6667

Explanation:

<u>For helium gas:</u>

Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 3.0 L

V₂ = 9.0 L

P₁ = 5.6 atm

P₂ = ?

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{5.6}\times {3.0}={P_2}\times {9.0} atm

{P_2}=\frac {{5.6}\times {3.0}}{9.0} atm

{P_1}=1.8667\ atm

<u>The pressure exerted by the helium gas in 9.0 L flask is 1.8667 atm</u>

<u>For Neon gas:</u>

Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 4.5 L

V₂ = 9.0 L

P₁ = 3.6 atm

P₂ = ?

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{3.6}\times {4.5}={P_2}\times {9.0} atm

{P_2}=\frac {{3.6}\times {4.5}}{9.0} atm

{P_1}=1.8\ atm

<u>The pressure exerted by the neon gas in 9.0 L flask is 1.8 atm</u>

<u>Thus total pressure = 1.8667 + 1.8 atm = 3.6667 atm.</u>

What are the flocculation basins?
Mila [183]

Answer:

flocculation is the operation in which the coagulated water must be gently mixed at a propeller speed of 15 to 20 rpm to promote the growth of the floc. ... The flocculation basin often has a number of compartments with decreasing mixing speeds as the water advances through the basin.

How many grams of mgcl2 is produced if 4. 67 moles of hcl react
frosja888 [35]

The mass of MgCl₂ produced is 5.685 grams.

<h3>What is mass?</h3>

Mass is the quantity of matter of a physical body.

The reaction is

Mg   +   2HCl   →    MgCl₂ + H₂

2 mole of HCl

(2 × 36.458) = 72.8 g        

                   

1 moles of MgCl₂

(1 × 95.21 g) = 95.21 g

1 g  Mg will produce = \dfrac{95. 21}{78.2}

4.67 mol Mg will produce

\dfrac{95. 21}{78.2} \times 4.67 = 5.685

Thus, the mass of MgCl₂ produced is 5.685 grams.
