Answer:
The equilibrium partial pressure of NO2 is 0.152 atm
Explanation:
Step 1: Data given
Initial pressure of NO2 = 0.500 Atm
Total pressure inside the vessel at equilibrium = 0.674 atm
Step 2: The balanced equation
2 NO2(g) ⇌ 2 NO(g) + O2(g)
Step 3: The initial pressures
pNO2 = 0.500 atm
pNO = 0 atm
pO2 = 0 atm
Step 4: The pressure at the equilibrium
pNO2 = 0.500 - 2x
pNO = 2x
pO2 = x
Total pressure = 0.674 = (0.500 - 2x) + 2x + x
0.674 = 0.500 + x
x = 0.174
pNO2 = 0.500 - 2*0.174 = 0.152 atm
pNO = 2x = 0.348 atm
pO2 = x = 0.176 atm
The equilibrium partial pressure of NO2 is 0.152 atm
Answer:- A. 
and 
Explanations:- In general, 
In acid-base reaction the acid gives hydrogen ion and the base gives hydroxide ion and these ions combine to form water. Rest of the ions from acid and base combine to form the salt.
Nitric acid breaks to give hydrogen ion and nitrate ion. Similarly, NaOH breaks to give sodium ion and hydroxide ion. Since, hydrogen ion and hydroxide ions form water, the sodium ion and nitrate ion forms the salt, sodium nitrate.
The reaction is shown as:
So, the right choice is A.
