Answer:
C. will precipitate out first
the percentage of remaining = 12.86%
Explanation:
Given that:
A solution contains:
From the list of options , Let find the dissociation of
where;
Solubility product constant Ksp of is
Thus;
replacing the known values in order to determine the unknown ; we have :
The dissociation of
The solubility product constant of is
The dissociation of is :
Thus;
Thus; the phosphate anion needed for precipitation is smaller i.e in than in
Therefore:
will precipitate out first
To determine the concentration of when the second cation starts to precipitate ; we have :
This implies that when the second cation starts to precipitate ; the concentration of in the solution is 0.00566
Therefore;
the percentage of remaining = concentration remaining/initial concentration × 100%
the percentage of remaining = 0.00566/0.0440 × 100%
the percentage of remaining = 0.1286 × 100%
the percentage of remaining = 12.86%
The experimental absolute zero value is less when compared to the accepted value of absolute zero.
<h3>What is absolute zero?</h3>
Absolute zero is defined as the temperature in which the lowest energy possible is attained in a thermodynamic system.
Absolute zero temperature has an accepted values of 0 Kelvin or -273.15 degrees Celsius.
At absolute zero, it is assumed that the volume of an ideal gas becomes zero. However, it has not been possible to cool any gas to absolute zero.
Based on the graph of temperature against volume of gases, the experimental absolute zero extrapolated from the graph where volume of the gases becomes zero is -285 degrees Celsius.
Therefore, the experimental absolute zero value is less when compared to the accepted value.
