If one starts with pure NO 2 (g) at a pressure of 0.500 atm, the total pressure inside the reaction vessel when 2NO 2 (g) 2NO(g) O 2 (g) reaches equilibrium is 0.674 atm. What is the equilibrium partial pressure of NO 2

the millers tale is the answer.

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

i think its 100

i hope this !
