The chemical equation would be:
2NO(g) + O2(g) --> 2NO2 (g)
<span>At equilibrium state, the partial pressure of the gases would be as follows : </span>
<span>NO = 522 - 2x </span>
<span>O2 = 421 - x </span>
<span>NO2 = 2x </span>
<span>- - - - - - - - - - - - -</span>
<span>943 - x = 748 </span>
<span>x = 195</span>
Calculating for Kp,
<span>Kp = (NO2)^2/ ((NO)^2 * (O2)) </span>
<span>Kp = (2 * 195)^2/ ((522 - 2 * 195)^2 * (421 - 195)) </span>
<span>Kp = 0.0386 </span>
Claim is : chemical reactions are smaller
It’s made using wool because it compresses the coldest air there is and not get it to be trapped in the body
Answer:

Explanation:
Data:
I = 2.15 A
t = 8 min 24 s
T = 26.0 °C
V = 65.4 mL
p = 774.2 To
1. Write the equation for the half-reaction
2H₂O ⟶ O₂ + 4H⁺ + 4e⁻
2. Calculate the moles of oxygen
V = 0.0654 L
T = (26.0 + 273.15) K = 299.15 K

3. Calculate the moles of electrons

4. Calculate the number of coulombs
t = 8 min 24 s =504 s
Q = It = 504 s × 2.10 C·s⁻¹= 1058 C
5. Calculate the number of electrons

6. Calculate Avogadro's number
