1. In a solution, made by dissolving 200 grams of sugar in 1000 grams of water, which component is considered to be solve?
a. sugar to solvent
b. both water and sugar are solvents in this example
c. water is solvent
d. the solvent cannot be determined from the information given
2. If a solute is to be soluble in a given solvent, which step in the solution making process must have a negative value for its energy?
a.the physical seperation of solute particles
b.the formation of solvent solute interactons
c. the physical separation of solvent paraticle
d. all three of the preceeding steps must be negative value for its energy?
3. Which of the following examples demonstrates a net decress in entropy?
a. adding cream to hot coffee
b. assembling a 1000-piece jigsaw puzzle
c. melting an ice cube
d. ripping a finishing jigsaw puzzle
e. all of the preceding are examples of net increase entrophy.
Thank u for helping me.
