LATEST 2025 CHEM 151 WITH Q&A VERIFIED ANSWERS COMPLETE The solubilities of Compounds A and B (in grams per 100 g of water) are shown in the figure below. Which of the statements is INCORRECT? If 35g of Compound A was dissolved in 100 g of water at 20 degrees C, it would be a supersaturated solution Which of these is the predicted order for INCREASING solubility (i.e., lowest to highest) in water? CH3CH2CH2CH3< CH3CH2CH2NH2<CH3CH2NH2 Indicate which aqueous solution has the lowest freezing point. NOTE: Assume no ion-pairing occurs? 0.3 m SrCl2 Which statement below regarding solubility is FALSE? Most ionic compounds are miscible with water Which of the following statements about colligative properties is FALSE? The predicted van't Hoff factor is always > or equal to 2 for nonelectrolytes The energy diagram below shows two different pathways (A and B) for the same reaction. Which statement is INCORRECT? Pathway A represents the catalyzed reaction For the reaction indicated below, you observe the concentration of B2 and calculate the average rate of change to be -0.36 M/s. What is the average rate of change of [A] for the same interval of time (i.e., change in [A]/ change in time? 2 MA2 + 3 B2 ---> 2 MB3 + 4 A +0.48 M/s A proposed mechanism for the following overall reaction is shown below: Overall: AX2 + 2 BY --> AY2 + 2 BX Step 1: AX2 + BY --> AXY + BX (slow) Step 2: AXY + BY ---> AY2 + BX (fast)
