homogenous mixture
H2O refers to water. In this solution, 100g of water was used to dissolve 2g of KCl.
Iodine solution is typically prepared by dissolving iodine crystals in a mixture of potassium iodide and distilled water. The potassium iodide acts as a stabilizer for the iodine. The final concentration of iodine in the solution can vary depending on its intended use.
First, calculate the moles of KCl: 40.0 g / 74.55 g/mol = 0.536 mol. Then calculate the moles of water: 225 g / 18.015 g/mol = 12.49 mol. The total moles of solute and solvent is 0.536 + 12.49 = 13.03 mol. Finally, calculate the mole fraction of KCl: 0.536 mol / 13.03 mol = 0.041.
The concentration of the resulting solution is calculated by adding the mass of the solute to the final volume of the solution. In this case, the 12.00 mL sample contains 13.3g of ammonium sulfate. When diluted to a total volume of 12.00 mL + 57.00 mL = 69.00 mL, the concentration of the resulting solution can be determined.
Calcium is different from all other elements in Group 2 of the periodic table because it has a higher electronegativity and a stronger metallic character compared to the other elements in the group, such as magnesium and strontium. Additionally, calcium has a higher ionization energy and a greater tendency to form ionic compounds compared to the other Group 2 elements.

The answer is 0,0207 mol.
13,75 % NaCl
This industry classification comprises establishments primarily involved in manufacturing prepared mixes and dough's from purchased flours.
The percent concentration is 13,75 %.
Cause
No, it is not. It is an adjective (prepared) or a verb (to make ready, to prepare).
The appositive phrase in the sentence "my father prepared his favorite entree" is "his favorite entree." An appositive typically provides additional information about a noun, and in this case, it describes what kind of entree the father prepared. However, there is no distinct appositive structure in this sentence as it stands; it simply describes an action.
