Thank you! what effect increasing CaCl. the charge of the metal ion has on the solubility in water of KCI compared with A3. a. The solubility of KCI is greater than that of CaCl, duc to stronger C the KCI. Coulombic forces in solubility of KCI is greater than that of CaCl, due to weaker Coulombic forces in the KCI. e. The solubility of KCI is less than that of CaCl, due to weaker Coulombic forces in the d. The solubility of KCI is less than that of Cacl, due to stronger Coulombic forces in the 10. A certain mass of neon gas is contained in a rigid steel container. The same mass of helium gas is KCI. KCI A this container. Which of the following best describes what happens? Assume the temperature is constant The pressure in the container increases but does not double b. The pressure in the container more than doubles. c. The pressure in the container does not change. d. The pressure in the container doubles. which of the following is a reasonable estimate for the volume of a balloon that has been filled with is g of oxygen gas at STP? a. 501 b. 200 L . I0 L Two gases are removed from their original container and placed into a third container, where they react with each other. All three containers have identical volumes, and all gases are at the same 12. temperature. Which container has the lowest pressure? a. Container C after the reaction b. Container A before the reaction They all have the same pressure d. Container B before the reaction

Explanation / Answer

Ans 9 B) The solubility of KCl is greater than that of CaCl2 due to weaker coulombic forces in the KCl.

The coloumbic forces in the ionic molecule is directly related to the ionic charges of the metal ions. Since the charge of K is +1 and that of Ca is +2 , the latter has more coloumbic force in between its ions and hence does not dissociate easily.
