<u>Answer:</u> The correct answer is 0.745 km
<u>Explanation:</u>
We are given:
A numerical value of 815 yards
To convert this into kilometers, we use the conversion factor:
1 km = 1093.6 yards
Converting the given value into kilometers, we get:
Hence, the correct answer is 0.745 km

Answer:
0.051
Explanation:
Let's consider the following reaction.
2 SO₂(g) + O₂(g) ⇄ 2 SO₃(g)
We can compute the pressures using an ICE chart.
2 SO₂(g) + O₂(g) ⇄ 2 SO₃(g)
I 3.3 0.79 0
C -2x -x +2x
E 3.3-2x 0.79-x 2x
The partial pressure of sulfur trioxide gas is 0.47 atm. Then,
2x = 0.47
x = 0.24
The pressures at equilibrium are:
pSO₂ = 3.3-2x = 3.3-2(0.24) = 2.82 atm
pO₂ = 0.79-x = 0.79-0.24 = 0.55 atm
pSO₃ = 0.47 atm
The pressure equilibrium constant (Kp) is:
Kp = pSO₃² / pSO₂² × pO₂
Kp = 0.47² / 2.82² × 0.55
Kp = 0.051
Answer:
No of moles of carbon = 9.63 mol
Explanation:
No of atoms of carbon = 5.8 × 10²⁴
Avogadro's no. = 6.022 × 10²³
No. of moles = No. of atoms / Avogadro's no.
N = 5.8 × 10²⁴ / 6.022 × 10²³
N = 9.63 mol
∴ No of moles of carbon = 9.63 mol
