The value of ΔH° for the reaction below is -126 kJ. kj are released when 2.00 mol of NaOH is formed in the reaction? 2 Na2O2 (s) + 2 H2O (l) → 4NaOH (s) + O2 (g)

A) 252
B) 63
C) 3.9
D) 7.8
E) -126

"63" kj are released. A further solution is provided below.

The equation is:

Value of ΔH,

As we know,

Now,

→

→    

→      

→            

Thus the above response is correct.

Its D.

clouds form

solid ice forms on leaves.

water droplets form on grass.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
