Station 4 - page 3 Sophia saw a TV show where they said they could make baby carrots float in water and she wanted to try at home. She put 150.0 ml of water in a glass and added a baby carrot. It settled to the bottom of the cup. She measured salt with an electronic scale and continued adding and stirring until the carrot did float in the water! She added 7.0 g of salt in...

answer 1-4
Which of the following (a-d) is TRUE regarding solid NaCl dissolving in water The attraction of the water to the ions in NaCl is through dipole-dipole IFs. Water is considered the solute and NaCl the solvent. The partially positive oxygen in water is attracted to the chloride ion. d. The process of separating the sodium ions from the chloride ions is endothermic. All of these statements are true. polar For the following solution, describe the deviation with respect...

QUESTION 4
If you take a 171 mL of a 1.4 M NaCl solution and dilute it to
500 mL, what is the molarity of the final solution?
Enter the numerical answer in decimal notation
QUESTION 10
Information - Colligative
Properties
Colligative properties of solutions are those properties which
depend only on the number of dissolved solute particles in solution
not the chemical properties of the solute. For example when a
solute is dissolved in a solvent, vapor pressure

Question 9 1 pts Logan Roy is spending all his money income by buying mineral water and popcorn. At his current consumption level, the marginal utility of mineral water is 70 and the marginal utility of popcorn is 60. The price of a bottle of mineral water is $2.00 and the price of a box of popcorn is $1.50. The utility-maximizing rule suggests that Logan should: O Increase consumption of popcorn and increase consumption of mineral water Decrease consumption of...
