Answer;
2M CaCl2 because it will dissociate into 3 ions making the solute concentration and the greatest of the options
Explanation;
-Osmotic pressure is the pressure that would have to be applied to a pure solvent to prevent it from passing into a given solution by osmosis, often used to express the concentration of the solution.
-CaCl2 is going to be higher because it dissolves into 3 particles, 2 Cl's and 1 Ca, whereas others like NaCl dissolves into only Na and Cl. so the concentration of CaCl2 is going to be higher.

Acid Rain is a result of chemical compounds, like sulfur dioxide and nitrogen oxide, are released into the air. These compounds rise high into the atmosphere and react with the different elements and compounds in the air, such as oxygen and water. This reaction forms acidic pollutants and eventually fall back to the ground as acid rain. This phenomenon is attributed to industrial waste; and it was especially common in the wake of the Industrialization Era of the United States.
Answer:<u> G1, S, and G2</u>
Explanation: Typically interphase lasts for at least 91% of the total time required for the cell cycle. Interphase proceeds in three stages, G1, S, and G2, followed by the cycle of mitosis and cytokinesis.
