Hot air balloons are open at their lower and end. A basket is suspended from the balloon and can take several passengers as well

as the pilot. A propane burner fixed to the basket is used to heat up the air in the balloon A hot balloon has a volume of 1500 m3 and its volume does not change when the enclosed air is heated.
1) Use the ideal gas equation, pV=nRT. to calculate how many molecules of the balloon contains at a temperature of 10 °C and a pressure 10.1 KP.
2) Calculate the mass of air it contains, assuming an average M of 29.​

Answer:

using pv=nRt

Explanation:

p= 10.1 kp

v= 1500m3

n=?

R= 8.314

T= 10 + 273= 283k

pv = nRt

10.1 *1500=n*8.314*283

n= 10.1*1500/8.314*283

n= 15150/2352.862

n= 6.44 moles

2) n= mass/ molar mass

6.44= mass/ 29

mass= 29* 6.44

mass= 186.76g

(a) The number of molecules contained by the balloon at the given condition is 6,438.97 moles.

(b) The mass of air in the balloon is 186.73 kg.

The given parameters;

  • <em>volume of the balloon, V = 1500 m³</em>
  • <em>temperature, T = 10⁰C = 273 + 10 = 283 K</em>
  • <em>pressure, = P = 10.1 kPa = 10,100 Pa</em>

The number of molecules contained by the balloon at the given condition is calculated as follows;

PV = nRT

where;

  • <em>R is ideal gas constant = 8.314 J/mol.K</em>
  • <em>n is the number of moles air in the balloon;</em>

n = \frac{PV}{RT} \\\\n = \frac{10,100 \times 1500}{8.314 \times 283} \\\\n = 6,438.97 \ moles

The mass of air in the balloon is calculated as;

n = \frac{m}{M} \\\\m = nM\\\\m = 6,438.97\ moles \ \times \ 29 \ g/mol\\\\m = 186.73 \ kg

What is the concentration of silver ions where silver iodide, Agl, is in a solution of hydroiodic
jonny [76]

Answer:

[Ag^+]=2.82x10^{-4}M

Explanation:

Hello there!

In this case, for the ionization of silver iodide we have:

AgI(s)\rightleftharpoons Ag^+(aq)+I^-(aq)\\\\Ksp=[Ag^+][I^-]

Now, since we have the effect of iodide ions from the HI, it is possible to compute that concentration as that of the hydrogen ions equals that of the iodide ones:

[I^-]=[H^+]=10^{-3.55}=2.82x10^{-4}M

Now, we can set up the equilibrium expression as shown below:

Ksp=8.51x10^{-17}=(x)(x+2.82x10^{-4})

Thus, by solving for x which stands for the concentration of both silver and iodide ions at equilibrium, we have:

x=[Ag^+]=2.82x10^{-4}M

Best regards!

A LA TEMPERATURA DE 35°C, UNA MUESTRA DE DIOXIDO DE CARBONO OCUPA UN VOLUMEN DE 350 ML. ¿Qué CAMBIO DE VOLUMEN SE PRODUCIRA SI L
Kisachek [45]

Answer:

New volume = 150 mL

Explanation:

Initial temperature, T₁ = 35°C

Initial volume, V₁ = 350 mL

We need to find the change in volume when the temperature drops to 15°C.

The relation between the temperature and the volume is given by Charle's law. Let new volume is V₂. It can be given by :

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{350\times 15}{35}\\\\V_2=150\ mL

So, the new volume is 150 mL.
