Answer:
221 °C
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 4.1 L
Initial temperature (T₁) = 25 °C
= 25 °C + 273
= 298 K
Final volume (V₂) = 6.8 L
Final temperature (T₂) =?
The final temperature of the gas can be obtained as follow:
V₁ / T₁ = V₂ / T₂
4.1 / 298 = 6.8 / T₂
Cross multiply
4.1 × T₂ = 298 × 6.8
4.1 × T₂ = 2026.4
Divide both side by 4.1
T₂ = 2026.4 / 4.1
T₂ ≈ 494 K
Finally, we shall convert 494 K to celcius temperature. This can be obtained as follow:
°C = K – 273
K = 494
°C = 494 – 273
°C = 221 °C
Thus the final temperature of the gas is 221 °C
Answer:
Temperature = 6.91K
Explanation:
Temperature = T
Number of Moles = 2.49moles
Volume = 1.0L
Pressure = 143kPa
R = 8.31kPa*L/mol.K
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume which the gas occupies
n = number of moles of the gas
R = ideal gas constant
T = temperature of the ideal gas
PV = nRT
T = PV / nR
T = (143 * 1) / (2.49 * 8.31)
T = 143 / 20.6919
T = 6.91K
The temperature of the gas is 6.91K
The answer is (3). Neon atoms have a stable valence electron configuration. This is a characteristic of Group 18 elements. This makes these elements not easy to react with other substances.
A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above. Offshore volcanoes form islands, resulting in a volcanic island arc.
<span>When a strong acid is in equilibrium, it dissociates into ions including a proton, H+ and an anion, which could be Cl-, Br-, SO42-, NO3-, etc. A strong acid dissociates completely unlike the weak ones. This means the concentration of the acid produces the same concentration of H+ and the anion.</span>
