The answer is 546K. If you need the answer in degrees Celsius you subtract 273 from 546 and get 273 degrees Celsius. I included how I got the answer in the photo below. Hope this helps!
Answer:
328.1 K.
Explanation:
- To calculate the no. of moles of a gas, we can use the general law of ideal gas: <em>PV = nRT</em>.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in.
- If n is constant, and have two different values of (P, V and T):
<em>P₁V₁T₂ = P₂V₂T₁</em>
<em></em>
P₁ = 1.0 atm (standard P), V₁ = 72.1 L, T₁ = 25°C + 273 = 298 K (standard T).
P₂ = 93.6 kPa = 0.924 atm, V₂ = 85.9 L, T₂ = ??? K.
<em>T₂ = P₂V₂T₁/P₁V₁ = </em>(0.924 atm)(85.9 L)(298 K)/(1.0 atm)(72.1 L) <em>= 328.1 K.</em>

Carbon because it is not stable
Answer:
The half cell reaction when it used as an anode
H₂(g) → 2 H⁺ + 2 e⁻
Explanation:
Standard hydrogen electrode used as reference electrode & acts as an cathode as well as anode half cell.
The half cell reaction when it used as an anode
H₂(g) → 2 H⁺ + 2 e⁻
(Pressure should be 1 bar , temperature 273 k and concentration of HCl = 1 Molar)
Cell representation
H₂(g) , H⁺(1 M)
The standard electrode potential i.e oxidation as well as reduction = 0.00 V
