Answer:
The answer to your question is Theoretical yield
Explanation:
Theoretical yield is the quantity of a product obtain considering that all the reactants will be converted into products. The theoretical yield considers that the reaction is 100% effective, but this is not true most of the chemical reactions have a yield of 80 % or lower.
One substance can be separated from another through physical means
Ionic compound are those compounds which are made up of ions. The ion which has tendency to loose electrons is said to cation (positive charge) such as metals whereas ion which has tendency to gain electrons is said to anion (negative charge) such as non-metals.
Calcium nitrate is quite soluble in water due to very low lattice enthalpy in comparison to other ionic compound. With lower lattice enthalpy, less energy is required for the dissociation of calcium nitrate and it get dissolves in water than other three compounds. Moreover, hydration energy is higher for calcium nitrate which make its solubility higher in water than other ionic species.
Thus, is correct answer.
It it Asthenosphere because it is the closest to the core ans is comprised of magma
