A steel cylinder contains a mixture of nitrogen, oxygen, and carbon dioxide gases. The total pressure in the tank is 2710 torr. The pressure exerted by the nitrogen and oxygen is 930 and 850 torr, respectively. What is the partial pressure in torr of the carbon dioxide in the mixture

Answers

Answer 1

A steel cylinder contains a mixture of nitrogen, oxygen, and carbon dioxide gases. The total pressure in the tank is 2710 torr. The pressure exerted by the nitrogen and oxygen is 930 and 850 torr, respectively.  27.1 torr is the partial pressure of the carbon dioxide in the mixture.

What is Dalton's Law of Partial Pressure ?

Dalton's Law of partial pressure states that the total pressure exerted by non reacting gaseous mixture at a constant temperature and given volume is equal to the sum of partial pressure of all gases.

It is expressed as:

[tex]P_{A} = X_{A} P_{T}[/tex]

where,

[tex]P_{A}[/tex] = Partial pressure of gas A

[tex]X_{A}[/tex] = Mole fraction of gas A

[tex]P_{T}[/tex] = Total pressure

Mole Fraction of Nitrogen

= [tex]\frac{930}{930 + 850}[/tex]

= 0.52

Mole Fraction of Oxygen

= [tex]\frac{850}{850 + 930}[/tex]

= 0.47

Now,

Mole fraction of nitrogen + Mole fraction of oxygen + Mole fraction of carbon dioxide = 1

⇒ 0.52 + 0.47 + Mole fraction of carbon dioxide = 1

⇒ 0.99 + Mole fraction of carbon dioxide = 1

⇒ Mole fraction of carbon dioxide = 1 - 0.99

⇒ Mole fraction of carbon dioxide = 0.01

Now put the value in above expression we get

[tex]P_{A} = X_{A} P_{T}[/tex]

     = 0.01 × 2710

     = 27.1 torr

Thus from the above conclusion we can say that A steel cylinder contains a mixture of nitrogen, oxygen, and carbon dioxide gases. The total pressure in the tank is 2710 torr. The pressure exerted by the nitrogen and oxygen is 930 and 850 torr, respectively.  27.1 torr is the partial pressure of the carbon dioxide in the mixture.

How many mL of a 1.00 M HCl solution would need to be added to 100 mL of 0.263 M ammonia to produce a buffer with a pH of 10.00. The pKa of ammonia is 9.25.

Answers

Answer:

3.97mL of 1.00M HCl must be added

Explanation:

The buffer of ammonia and ammonium ion follows the equation:

pH = pKa + log [NH₃] / [NH₄⁺] (1)

Where pH is the pH we want to obtain: 10.00

pKa is the pKa of the buffer: 9.25

[NH₃] could be taken as moles of ammonia

And NH₄⁺ moles of ammonium ion

When NH₃ reacts with HCl:

NH₃ + HCl → NH₄⁺ + Cl⁻

NH₄⁺ is produced. That means moles of ammonia are Initial moles of ammonia - Moles of HCl added

Moles of HCl added = Moles of ammonium ion

The total moles of the buffer are:

0.100L * (0.263mol / L) = 0.0263moles = [NH₄⁺] + [NH₃] (2)

Rewriting (1):

10.00 = 9.25 + log [NH₃] / [NH₄⁺]

0.75 = log [NH₃] / [NH₄⁺]

Replacing (2) in (1):

0.75 = log 0.0263 -  [NH₄⁺] / [NH₄⁺]

5.6234 = 0.0263 -  [NH₄⁺] / [NH₄⁺]

5.6234[NH₄⁺] = 0.0263 - [NH₄⁺]

6.6234[NH₄⁺] = 0.0263

[NH₄⁺] = 0.00397 moles = Moles HCl

To obtain these moles we must add:

0.00397 moles HCl * (1L / mol) = 0.00397L =

3.97mL of 1.00M HCl must be added

balance Ca(NO3)2 + NaCl ---> NaNO3 + CaCl2

Answers

Answer:

Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2

Explanation:

On the left you have an original balance of Ca - 1, N - 2, O - 6, Na - 1, and Cl - 2, and on the right you have a balance of Ca - 1, N - 1, O - 3, Na - 1, Cl - 2.

Ca - 1 Ca - 1

N - 2 N - 1

O - 6 O - 3

Na - 1 Na - 1

Cl - 1 Cl - 2

In order to balance these, you'll have to make both sides equal. To get the N on the right to be equal to the N on the left, you'll have to multiply NaNO3 by 2, thus making it 2NaNO3. By doing this, you will offset the balance of both Na and O.

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 1 Na - 2

Cl - 1 Cl - 2

To balance the rest of the equation, you'll have to multiply both Na and Cl by 2. This will change NaCl to 2NaCl, making the balance look like this:

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 2 Na - 2

Cl - 2 Cl - 2

You will now be left with your final equation Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2.

Which statement best compares the melting points of magnesium and sodium?

a
Magnesium has a higher melting point because it contributes one additional electron per atom than sodium in the electron sea.
b
Sodium has a higher melting point because it contributes one fewer electron per atom than magnesium in the electron sea.
c
Sodium has a higher melting point because it contributes two fewer electrons per atom than magnesium in the electron sea.
d
Magnesium has a higher melting point because it contributes two additional electrons per atom than sodium in the electron sea.

Answers

A because according to electron sea theory magnesium shares two valence electrons in electron sea while sodium shares one suggesting that magnesium has stronger metallic bond than sodium so breaking metallic bond in magnesium will require more energy as compared to breaking metallic bond in sodium

The melting point of magnesium is higher than the melting point of sodium because it contributes two additional electrons per atom than sodium in the electron sea. Thus option d is correct.

What is melting point?

Melting point of a substance is the temperature at which it converts from solid state to liquid state where, the two phases are in equilibrium. Melting point is affected by the bond type, molecular weight, temperature and pressure.

Melting point of elements increases along a period because the atomic size is decreasing along the period and molecular weight is increasing. Thus, the nuclear attractive pull increases resulting in higher energy needed to break the attractive force.

Magnesium is 12th element and sodium is 11th element. Thus magnesium is smaller than sodium and have one more electron than sodium. Thus magnesium have high molecular weight and high nuclear attraction leads to its higher melting point.
