The density of hydrogen : ρ = 0.0892 g/L
<h3>Further explanation</h3>Given
mass of Hydrogen : 0.446 g
Volume = 5 L
Required
The density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³, kg/m³, or g/L
Density formula:
Input the value :
ρ = m : V
ρ = 0.446 g : 5 L
ρ = 0.0892 g/L
Answer:
NaCl.
Explanation:
In the solution, ZnSe ionizes to and
. Following reaction represents the ionization of ZnSe in solution -
⇄
As we want to increase the solubility of ZnSe, we must decrease the concentration of dissociated ions so that the reaction continues to forward direction.
If we add NaCl to this solution, then we have and
in the solution which will be formed by the ionization of NaCl.
Now, in the solution will react with two
ions to form
as follows -
⇄
Due to this reaction the concentration of will decrease in the solution and more ZnSe can be soluble in the solution.
