Solution Steps

Step 1: Analyze Statement 1

Statement 1 claims that the freezing point of the solution decreases as the concentration of the solute increases. This is a true statement. According to the colligative properties of solutions, the freezing point of a solution is lowered when a nonvolatile solute is added. This phenomenon is known as freezing point depression, and the extent of the depression is directly proportional to the molal concentration of the solute.

Step 2: Analyze Statement 2

Statement 2 claims that the boiling point of the solution is independent of the concentration of the solute. This is a false statement. The boiling point of a solution increases when a nonvolatile solute is added, a phenomenon known as boiling point elevation. The increase in boiling point is also a colligative property and is directly proportional to the molal concentration of the solute.

Final Answer

The correct answer is (C) 1 is true while 2 is false.

\(\boxed{\text{C}}\)

Suppose that you decide to borrow 16,000 for a new car. You can select one of the following loans, each requiring regular monthly payments. Installment Loan A: three-year loan at 5.1% Installment Loan B: five-year loan at 4.8% Use PMT = (rl) / [1 - (1 + r/n)^(-nt)] to complete parts (a) through (c) below. b. Find the monthly payments and the total interest for Loan B. The monthly payment for Loan B is 288.29. (Do not round until the final answer. Then round to the nearest cent as needed.) The total interest for Loan B is 1297.40. (Round to the nearest cent as needed.)
