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%
Composer and performer of Old Occitan lyric poetryduring the High Middle Ages (1100–1350). Since the word troubadour is etymologically masculine, a female troubadour is usually called a trobairitz.
D! the molecules of the warmer water would have a higher average kinetic energy :)
Answer: Food Chain
Explanation: In a food chain, energy is passed from one link to another. Many organisms cannot make their own food, so rely on eah other for nourishment.
