Part IV. Henry's Law More Carbon dioxide gas will dissolve (or stay dissolved) in water when pressure is (high or low?)  .Dissolved Carbon dioxide leaves water when the pressure is (high or low?)

Explain why some compounds don’t gain or lose heat when they dissolve (in water). How are they different from those compounds that did gain or release heat?

23. What is the normality of 1.00 L of a sodium hydroxide solution that contains 28.6 g of NaOH? a. 1.40 N b. 28.6 N ©0.358 N d. 0.715 N e. none of these

A. Causes more gaseous solvent to be forced into a liquid. 1. Dissolve B. Increases solubility by moving the molecules around faster. 2. Pressure C. Increases solubility by allowing the solvent to touch more sides of the solute. 3. Crushing 4. Heating D. Expands the solvent a bit to allow more room for the solute. 5. Stirring E. When something seems to disappear inside a solvent. Polar or Non-polar? Cooking oil Salt Soluble in water Ionic Compounds A compound with H's Dissolves in water Sugar Insoluble in water ive Draw a water molecule, being sure to label the ends as positive and negative. up Do metals beome positive er negalive? Would a meal be attracted to water's hydrogens or oxygen? Would a nonmetal be attracted to water's hydrogens or oxygen?

Which of the following statements about the dissolving process is accurate?   Select one: a. Surfactant ions have a hydrophilic end that is repelled by water. b. For a substance to dissolve, solute-solvent attractions must overcome the attractions within both solute and solvent c.  Immiscible liquids mix to form a solution. d. Solutes dissolve in solvents of dissimilar polarities.

what happens when you put a mixture of rubbing alcohol and water on baking soda?

5. A 100-kilogram salt solution originally 4% by weight. Salt in water is boiled to reduce water content until the concentration is 5% by weight salt. How much water is evaporated? A. 10 B. 15 C. 20 D. 25

14. An acid is called an acid because of the amount of positive hydrogen ions that are dissolved in the solution. Based on this concept, which substance has more hydrogen ions dissolved in the solution? (circle one for each) a. Vomit or chicken soup b. Hand soap or drain cleaner c. Blood or soda     15. A base is called a base because of the amount of hydroxide ions that are dissolved in the solution. Based on this concept, which substance has more hydroxide ions dissolved in the solution? (circle one for each) a. Milk or spit b. Blood or coffee c. soda pop or battery acid.

Where should heat be applied to a test tube?A) Bottom of the test tube.B) Top of the test tube.C) Middle of the test tube.D) The point at which the solution is highest in the tube.E) Anywhere is fine.

How does evaporation occur? Why does ice float? What is a solution?
