Answer: its 15 its none of those
Explanation:
They use natural resources like sunlight water they need soil water and sunlight to grow the stem should be pliable and firm and will have a green cast on the inside
Answer:
Explanation:
Moles of
= 1 mole
Moles of
= 1 mole
Volume of solution = 1 L
Initial concentration of
= 1 M
Initial concentration of
= 1 M
The given balanced equilibrium reaction is,

Initial conc. 1 M 0M 1 M
At eqm. conc. (1-2x) M (2x) M (1+x) M
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[NO]^2[Cl_2]}{[NOCl]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO%5D%5E2%5BCl_2%5D%7D%7B%5BNOCl%5D%5E2%7D)
The
= 
Now put all the given values in this expression, we get :

By solving the term 'x', we get :

Concentration of
at equilibrium= (2x) M =
Answer:
