The CO2 that builds up in the air of a submerged submarine can be removed by reacting it with sodium peroxide. 2 Na2O2 (s) + 2 CO2 (g) → 2 Na2CO3 (s) + O2 (g)
If a sailor exhales 150.0 mL of CO2 per minute at 20oC and 1.02 atm, how much sodium peroxide is needed per sailor in a 24 hr period?​

Answers

Answer 1

Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1.02 atm

V = Volume of gas = 150.0 ml = 0.15 L

n = number of moles  of carbon dioxide = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]20^0C=(20+273)K=293K[/tex]

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1.02atm\times 0.15L}{0.0821 L atm/K mol\times 293K}=0.006moles[/tex]

[tex]2Na_2O_2(s)+2CO_2(g)\rightarrow 2Na_2CO_3(s)+O_2(g)[/tex]

According to stoichiometry:

2 moles of carbon dioxide require = 2 moles of sodium peroxide

Thus 0.006 moles carbon dioxide require= [tex]\frac{2}{2}\times 0.006=0.006[/tex] moles of  sodium peroxide

Mass of  sodium peroxide needed for 24 hour=[tex]moles\times {\text {Molar mass}}=0.006mol\times 78g/mol\times 24\times 60=674g[/tex]

Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.

Answer 2

The amount (in grams) of sodium peroxide needed per sailor in a 24 hr period is 673.92 g

Determination of the mole of CO₂Volume (V) = 150 mL = 150 / 1000 = 0.15 L Temperature (T) = 20 °C = 20 + 273 = 293 KPressure (P) = 1.02 atmGas constant (R) = 0.0821 atm.L/Kmol Mole of CO₂ (n) =?

Using the ideal gas equation, we can obtain the mole of CO₂ as follow:

n = PV / RT

n = (1.02 × 0.15) / (0.0821 × 293)

n = 0.006 mole

How to determine the mole of Na₂O₂ required

2Na₂O₂ + 2CO₂ → 2Na₂CO₃ + O₂

From the balanced equation above,

2 moles of CO₂ required 2 moles of Na₂O₂.

Therefore,

0.006 mole of CO₂ will also require 0.006 mole of Na₂O₂.

How to determine the mass of Na₂O₂ required Mole of Na₂O₂ = 0.006 mole Molar mass of Na₂O₂ = (23×2) + (16×2) = 78 g/mol Mass of Na₂O₂ =?

Mass = mole × molar mass

Mass of Na₂O₂ = 0.006 × 78

Mass of Na₂O₂ = 0.468 g per minute

Mass of Na₂O₂ required for 24 h = 0.468 × 24 × 60 = 673.92 g

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.

If the pressure increases to 350 kPa and the volume remains constant, what will the new temperature be?

Round your answer to one decimal place.

Answers

Answer:

The new temperature will be 565.83 K.

Explanation:

Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.

In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:

[tex]\frac{P}{T} =k[/tex]

When an ideal gas goes from a state 1 to a state 2, it is true:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

P1= 180 kPaT1= 291 KP2= 350 kPaT2= ?

Replacing:

[tex]\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}[/tex]

Solving:

[tex]T2=350 kPa*\frac{291 K}{180 kPa}[/tex]

T2= 565.83 K

The new temperature will be 565.83 K.

? M KF

Answers

The new concentration : = 0.194 M

Further explanation

Given

115 mL(0.115 L) of a 2.35 M Potassium  fluoride (KF)

1.28 L of water

Required

The new concentration

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

M₁V₁=M₂V₂  

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = volume of the solution after dilution

V₂=0.115 + 1.28 = 1.395 L

Input the value :

M₂ = (M₁V₁)/V₂

M₂ = (2.35 x 0.115)/1.395

M₂ = 0.194

Answer: 0.194

Explanation:

Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.

In an atom, protons are held by strong nuclear forces.

Within an atom, protons are the positively charged particles. Together with the neutrons, they are found in the nucleus of an atom. The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is. Protons cannot be removed from an atom due to the strong binding force holding them together in place.
