For the reaction: 2 H3PO4 + 3 Ca(OH)2 → Ca3(PO4)2 + 6 H2O If you have 59.8 mL of 1.60 M phosphoric acid, how many mL of 0.500 M calcium hydroxide do you need to neutralize the acid?

Answers

Answer 1

Answer:

V = 127.57 mL

Explanation:

In this case, we are having an acid base titration, and this, according to the overall reaction:

2H₃PO₄ + 3Ca(OH)₂ -----> Ca₃(PO₄)₂ + 6H₂O

This reaction was neutralized, so, it's a neutralization reaction, therefore, we can use the following expression for neutralization reactions:

n₁ = n₂  (1)

This is because, in the equivalence point, both moles of the reagents are the same. Now we need to do a relation between this and the actual moles that we have according to the overall reaction.

In this case, we have 2 moles of acid reacting with 3 moles of base, so, the equation (1) is re-written like this:

2n₁ = 3n₂   (2)

Knowing this, and that we have values of concentrations and volume, we can write the expression of moles in terms of molarity and volume:

n = M * V    replacing in (2):

2M₁V₁ = 3M₂V₂   From here, we can solve for V₂ which is the volume of the base:

V₂ = 2M₁V₁ / 3M₂   (3)

Now, all we have to do is replace the given values to obtain the volume of the base:

V₂ = 2 * 1.6 * 59.8 / 3 * 0.5

V₂ = 127.57 mL
Answer 2

Answer:

[tex]V_{Ca(OH)_2}=0.287L=287mL[/tex]

Explanation:

Hello,

In this case, given the reaction:

[tex]2 H_3PO_4 + 3 Ca(OH)_2 \rightarrow Ca_3(PO_4)_2 + 6 H_2O[/tex]

We first compute the moles of phosphoric acid that are actually reacting given the volume (must be in litres) and the molarity:

[tex]n_{H_3PO_4 }=1.60\frac{mol}{L}*59.8mL*\frac{1L}{1000mL} =0.0957molH_3PO_4[/tex]

Next, we compute the moles of calcium hydroxide that are reacting by using the 3:2 molar ratio with phosphoric acid:

[tex]n_{Ca(OH)_2}=0.0957molH_3PO_4*\frac{3molCa(OH)_2}{2molH_3PO_4} =0.144molCa(OH)_2[/tex]

Finally, by knowing the 0.500 M of the calcium hydroxide solution we compute the required volume:

[tex]V_{Ca(OH)_2}=\frac{n_{Ca(OH)_2}}{M_{Ca(OH)_2}}=\frac{0.144mol}{0.500\frac{mol}{L} } \\ \\V_{Ca(OH)_2}=0.287L=287mL[/tex]

Best regards.

10) Intravenous saline solutions have a concentration of 1.5 M NaCl. How many liters of saline can be prepared from 50.0 g of NaCl?

Answers

Answer:

0.57 mol/L

Explanation:

Molarity (M) is defined as the number of moles of solute per liter of solution (moles/Liter).

Molarity  =  [tex]\frac{moles of solute}{liters of solution}[/tex] or Moles  =  molarity × litres

so, the mass of Nacl in 1 mol is 58.44 g,

Moles of NaCl = 50.0g x 1 mole NaCl / 58.44 g

                          = 0.855 mol NaCl

Moles  =  molarity × litres

0.855 = 1.5 M x L

L = 0.57 mol/L

Hence, 0.57 mol/L can be prepared from 50.0 g of NaCl.

A gas has a volume of 3.25 liters at 54 C and 231 kPa of pressure. At what temperature will the same gas take up 4.35 liters of space and have a pressure of 168 kPa?

Answers

Answer: 318 K

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 231 kPa

[tex]P_2[/tex] = final pressure of gas = 168 kPa

[tex]V_1[/tex] = initial volume of gas = 3.25 L

[tex]V_2[/tex] = final volume of gas = 4.35 L

[tex]T_1[/tex] = initial temperature of gas = [tex]54^oC=273+54=327K[/tex]

[tex]T_2[/tex] = final temperature of gas = ?

Now put all the given values in the above equation, we get:

[tex]\frac{231\times 3.25}{327}=\frac{168\times 4.35}{T_2}[/tex]

[tex]T_2=318K[/tex]

At 318 K of temperature will the same gas take up 4.35 liters of space and have a pressure of 168 kPa

3. (a) Move up

(b) 868 mmHg

4. 868 mmHg

5. 775 mmHg

6. Partial pressure of He is 0.64 atm.

Partial pressure of oxygen is 1.29 atm.

Partial pressure of N is 2.57 atm.

7. 445.72 torr.

Explanation:

1. To convert 321  torr to atmospheres

1  atmosphere = 760 torr

∴ 1 torr = 1/760 atmospheres

Hence, 321 torr = 321 × 1/760 = 321/760 atmospheres = 0.422 atmospheres

2. To convert 6.25 atmospheres to Pascals, we have;

1 atmosphere = 101325 Pascals

∴ 6.25 atmospheres = 6.25 × 101325 Pascals = 633281.25 Pascals

3. (a) Here we have, given that the value of the pressure on the bottle = 830 mmHg, when the valve is opened, the mercury in the open-end arm will move up because the pressure of the gas inside the flask is more than the pressure on the other side of the open-end arm

(b) After the mercury stops moving the difference between the two columns will be the difference between the two pressures, that is 830 mmHg - 745 mmHg = 85 mmHg

4. From the diagram, it is seen that the differenc beteen the two columns is 123 mm, therefore, the pressure in the flask is 123 mmHg more than the external pressure, hence the pressure of the as in the flask = 745 mmHg + 123 mmHg = 868 mmHg

5. Here we have that the height of the mercury in the open-end is less than the height of the mercury on the arm closer to the flask, therefore, the pressure of the gas in the flask = 825 mmHg - 50 mmHg = 775 mmHg

6. Number of moles of He = 1 mole

Number of moles of oxygen, O = 2 mole

Number of moles of nitrogen, N = 4 mole

From Dalton's law of partial pressure we have that, the total pressure of a given mass of gas is equal to the partial pressure of the individual gases

[tex]That \ is \ \chi _i = \frac{n_i}{n_{total}} \ and \ P_i = \chi_i \cdot P_{total}[/tex]

Hence;

Total number of moles = 1 + 2 + 4 = 7 moles

Mole fraction of He = 1/7

Partial pressure of He = 1/7×4.5 = 0.64 atm.

Mole fraction of oxygen, O = 2/7

Partial pressure of oxygen= 2/7×4.5 = 1.29 atm.

Mole fraction of N = 4/7

Partial pressure of N = 4/7×4.5 = 2.57 atm.

7. From Boyle's law

P₁×V₁ = P₂×V₂

Hence;

P₂ = P₁×V₁/V₂

Where:

P₁ = Initial pressure = 2.57 atm

V₁ = Initial volume =1.57 liters

V₂ = New volume = 6.88 liters

P₂ = New pressure = 2.57×1.57/6.88  = 0.59 atm.

To convert 0.59 atm. to torr, we multiply by 760 thus;

0.59 atm. = 0.59 × 760 torr = 445.72 torr.

A helium balloon contains 69.5 L of helium at sea level, where the atmosphere pressure is 101.3 kPa. The balloon is released frim a 4500 m mountaintop where the pressure is 61.7 kPa. What is the volume of the balloon when it takes off from the mountaintop

Answers

Answer:

THE NEW VOLUME WHEN THE BALLOON TAKES OFF FROM THE MOUNTAINTOP IS 114.1 L

Explanation:

The question follows Boyle's law of gas laws and it involves pressure and volume being inversely proportional to the volume. As pressure increases, the volume decreases and vice versa.

Mathematically represented as:

P1V1 = P2 V2

P1 = 101.3 kPa = 101.3 * 10^3 Pa

V1 = 69.5 L

P2 = 61.7 kPa = 61.7 * 10^3 Pa

V2 = ?

making V2 the subject of the formula. we have;

V2 = P1 V1 / P2

V2 = 101.3 *10^3 * 69.5 / 61.7 *10^3

V2 = 7040.35 / 61.7

V2 = 114.106 L

The volume at a decreased pressure of 61.7 kPa at the mountaintop is 114.1 L

This is in line with Boyle's law which shows that at high pressure, volume decreases and at low pressure, volume increases.

Answer:

The new volume is 114.1 L

Explanation:

Step 1: Data given

Volume of the helium balloon = 69.5 L

The atmosphere pressure is 101.3 kPa

The pressure decreases to 61.7 kPa

Step 2: Calculate the new volume

P1*V1 = P2*V2

⇒with P1 = the atmosphere pressure is 101.3 kPa

⇒with V1 = the initial volume = of the helium balloon = 69.5 L

⇒with P2 = the decreased pressure = 61.7 kPa

⇒with V2 = the new volume = TO BE DETERMINED

101.3 kPa * 69.5 L = 61.7 kPa *  V2

V2 = (101.3 kPA * 69.5 L ) / 61.7 kPa

V2 = 114.1 L

The new volume is 114.1 L

What is Hess' law?

Hess' law states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes.

To apply Hess' law in this case we have to:

Conserve equation 1 as is.Reverse equation 2 and multiply it by 1/2, thus changing the sign of its enthalpy and multiplying it by 1/2.Add both equations and their enthalpies.

Ca(s) + CO₂(g) + ½ O₂(g) → CaCO₃(s)    ΔH = -812.8 kJ

CaO(s) → Ca(s) + ½ O₂(g)                       ΔH = 634.5 kJ

Even though the molecules are moving at different speeds in the two cylinders, they have the same kinetic energy. Cylinder B contains molecules that are moving more slowly than the molecules in Cylinder A. Cylinder B contains a gas that has a temperature closest to absolute zero.

Answers

Answer:

The correct option is;

Cylinder A contains a gas that has a temperature closest to absolute zero

Explanation:

From the kinetic theory of gases, the average speed of a gaseous molecule is found from the following equation;

[tex]v_{rms} = \sqrt{\frac{3\cdot R \cdot T}{MW} }[/tex]

Where:

[tex]v_{rms}[/tex] = rms speed which is the square root of the average of the velocities of the gas molecules squared which is used in place of the average of the gas molecules as the sum of the velocities of all the gas molecules in the cylinder is zero

R = Universal gas constant = 8.3145 J/(mol·K)

MW = Molecular weight of the gas

Hence where we have;

[tex]v_{rmsA}[/tex] = Average velocity of gas A = 0.0000001 m/s

[tex]v_{rmsB}[/tex] = Average velocity of gas B = 0.3 m/s

Since, R and MW are constant for the gas in cylinder A constant, therefore, as [tex]v_{rmsA}[/tex] ≈ 0 m/s, the temperature, [tex]T_A[/tex], of gas A is closest to absolute zero.

Answers

Answer:

The particle represented by X(aq) is  A) H₂PO₄⁻(aq)

Explanation:

According to the Brønsted-Lowry Theory, a base is a substance capable of accepting protons (H⁺) in solution. Conversely, a substance acts as an acid if it acts as a proton donor.

A proton transfer then occurs, requiring the presence of a proton donor (an acid) and a base that accepts them.

When an acid gives up a proton, it becomes an anion, generating a conjugate base. That is, a conjugate base is an ion or molecule resulting from the acid that loses the proton. Conversely, a conjugated acid is an ion or molecule resulting from the base that the proton gains.

In this NH₃ / NH₄⁺ pair that NH₄⁺ is the conjugate acid of the NH₃ base, the latter acting as a base since it accepts a proton. H₃PO₄ then acts as an acid, yielding a proton and generating the conjugate base H₂PO₄⁻.

So, the particle represented by X(aq) is  A) H₂PO₄⁻(aq)
