How many moles of co2 are there in a 50.0 dm3 sample of the gas at a pressure of 100.0 kpa and a temperature of 50°c?
Rudiy27

Answer:

  • 609 mol

Explanation:

<u>1) Data:</u>

a) n = ?

b) V = 50.0 dm³ = 50.0 liter

c) p = 100.0 kPa

d) T = 50 °C

<u>2) Physical law:</u>

  • Ideal gas law: pV = nRT,

<u>3) Constants:</u>

  • R = 0.08206 atm-liter / K-mol

<u>4) Unit conversions:</u>

  • T = 50 + 273.15 K = 323.15 K

  • P = 100.0 kPa × (1 amt  /101,325 kPa) = 0.9869 atm

<u>5) Solution:</u>

  • pV = nRT ⇒ n = pV / (RT)

  • n = 0.9869 atm × 50.0 liter / (0.08206 atm-liter /K-mol × 323.15 K)

  • n = 609 mol ← answer

For the reaction given below, the frequency factor A is 8.7 1012 s−1 and the activation energy is 63 kJ/mol. NO(g) + O3(g) → NO2
Alex73 [517]

Answer:

K(70°C) = 2213.376 s-1

Explanation:

balanced reaction:

  • NO(g) + O3(g) → NO2(g) + O2(g)

∴ Ea = 63 KJ/mol

∴ A = 8.7 E12 s-1

∴ T = 70°C ≅ 343 K

Arrhenius eq:

  • K(T) = Ae∧(- Ea/RT)

∴ R = 8.314 E-3 KJ/K.mol

⇒ K(70°C) = (8.7 E12 s-1)e∧[-(63)/(8.314 E-3)(343)]

⇒ K(70°C) = (8.7 E12 s-1)*(2.5444 E-10)

⇒ K(70°C) = 2213.376 s-1

Block mountains form along which type of geological landform?
ozzi

Answer:

A. Fault blocks

Explanation:

The block mountains are formed by pieces of the crust that breaks down and pieces are pushed up by the movement of the crust around them.  These type of mountains usually have a steep and a slope side, due to the irregular nature of the fracture.  Example of such mountains are the Sierra Nevada mountains in North-America.

<u>They're not caused by the collision of two tectonic plates</u>, like most of the mountains of our planet.
