I don't know what model you're referring to so I can't answer the question. However, upon researching, I found a similar problem. I posted it as an attached picture. Looking at the model, the amount of grams a herbivore eat each day corresponds to the arrow pointing inwards. Since the label says 4.0 g, <em>the answer is 4 g per day</em>.
This is an incomplete question, here is a complete question.
A solution containing CaCl₂ is mixed with a solution of Li₂C₂O₄ to form a solution that is 3.5 × 10⁻⁴ M in calcium ion and 2.33 × 10⁻⁴ M in oxalate ion. What will happen once these solutions are mixed? Ksp (CaC₂O₄) = 2.3 × 10⁻⁹
A. Nothing will happen since both calcium chloride and lithium oxalate are soluble compounds.
B. Nothing will happen Ksp > Q for all possible precipitants.
C. A precipitate will form as calcium oxalate is not soluble to any extent.
D. A precipitate will form since Q > Ksp for calcium oxalate.
Answer : The correct option is, (D) A precipitate will form since Q > Ksp for calcium oxalate.
Explanation :
Concentration of =
Concentration of =
The equilibrium chemical reaction will be:
The solubility constant expression for this reaction is:
Now we have to calculate the ionic product for calcium oxalate.
From this we conclude that, that means a white solid precipitate of calcium oxalate will be formed when the solutions are mixed.
Hence, the correct option is, (D)
