Answer:
223 g
Explanation:
Molar mass Fe = 55.845 g/mol
mass=molar mass* number of moles=55.845*4.00≈223 g
Answer:
Kp of the reaction is 0.0215
Explanation:
Step 1: Data given
Partial pressure at the equilibrium of N2 = 0.22 atm
Partial pressure at the equilibrium of O2 = 0.19 atm
Partial pressure at the equilibrium of NO = 0.030 atm
Temperature = 2200 °C
Step 2: The balanced equation
N2(g) + O2(g) ⇌ 2NO(g)
Step 3: Calculate Kp
Kp = (pNO)² /(pO2)*(pN2)
Kp = (0.030)²/(0.19*0.22)
Kp = 0.0215
Kp of the reaction is 0.0215
THEY ARE ALL NONMETALS ARE THE CORRECTA NSWER
