Jenny dissolves as much salt as she can in 100 ml of room-temperature water. she learned in class that less salt will dissolve in cold water than in hot water. jenny adds some ice to the salt water and observes what happens. a. the effect is unpredictable because the ice changes two variables at the same time. b. it will allow more salt to be added to the solution because it adds water to the solution. c. it will force some of the salt to leave the solution because it will decrease the temperature. d. the ice will have no net effect on the amount of salt that can be dissolved in the solution.

Ascientist is working on an experiment for which she needs 20 liters of a 3.5% salt solution, the same salinity as ocean water. all she has in her lab are a 10% salt solution and a 1% salt solution. she decides to mix these to make her own 3.5% solution. how much of the 1% solution will she need to use?

Astudent has a 2% salt water solution and a 7% salt water solution. to best imitate salt water at a local beach, he needs 1 liter of a 3.5% salt water solution. he defines x as the amount of 2% solution and writes this equation: 0.2x + 0.7(x – 1) = 0.35(1) he solves the equation and determines that x is about 1.17 liters. he interprets this as needing 1.17 liters of 2% solution to make 1 liter of 3.5% solution. what errors did the student make? check all that apply.
