Answer:
1.89 V
Explanation:
To calculate the standard cell potential, subtract the reduction potential of the anode from the reduction potential of the cathode.
So for your calculation,
-0.22 V - (-2.11 V)= 1.89 V
Answer:
The pressure of CO2 at the equilibriumis 0.185 atm
Explanation:
Step 1: Data given
The value of Kp at that temperature is 0.242
FeO was initially in a container with CO at a pressure of 0.95 atm
Step 2: The balanceequation
FeO(s) + CO(g) ⟷ Fe(s) + CO2(g)
Step 3:The initial pressure
pCO = 0.95 atm
pCO2 = 0 atm
Step 4: The pressure at the equilibrium
pCO = 0.95 - x atm
pCO2 = X atm
Step 5: Calculate Kp
Kp = pCO2 / pCO
0.242 = X / (0.95 - X)
X = 0.185
pCO = 0.95 - 0.185 = 0.765 atm
pCO2 = 0.185 atm
The pressure of CO2 at the equilibriumis 0.185 atm
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together.
A solution contains 12 g of glucose in 240 mL of solution. What is the mass/volume % of the solution? 5.0% (m/v). Calculate the grams of KCl in 225 g of an 8.00 % (m/m) KCl solution
