Explanation:
Concentration of is 0.278 M and it is completely ionized into
and
.
This means that =
= 0.278 M
It is given that concentration of is 0.222 M.
As is a weak acid. Therefore, its dissociation will be as follows.
Initially : 0.222 M 0 0.278 M
Change : - x +x +x
Equilibrium : 0.222 M - x x 0.278 M + x
Therefore, dissociation constant for this reaction will be as follows.
Hence, putting the given values into the above formula as follows.
x = 0.00036
As, is 0.00036 M. Therefore, percentage ionization of
will be calculated as follows.
% ionization of =
=
= 0.16 %
Thus, we can conclude that % ionization of is 0.16%.

Explanation:
Given that,
Mass of marble slab is 38.6 kg or 38600 g
The dimensions of the slab is 23 cm × 17 cm ×4 cm
We know that the density of an object is given in terms of its mass volume as follows :
So, the density of the marble slab is
Answer:
Explanation:
Hello,
Based on the given chemical reaction, as 31.2 mL of hydrogen are yielded, one computes its moles via the ideal gas equation under the stated conditions as shown below:
Now, since the relationship between hydrogen and magnesium is 1 to 1, one computes its milligrams by following the shown below proportional factor development:
