(A) A liquid solution of A and B having equal mass fraction will have vapours at equilibrium having same mass fraction. (B) A liquid solution having mass % of A < 50% will have vapours having mass % of A > 50%. (C) A mixture present in the mass ratio of 2 : 3 can be separated into azeotropic mixture and pure B by fractional distillation. (D) A mixture present in the molar ratio of 2 : 3 can be separated into azeotropic mixture and pure B by fractional distillation.

Rosita has a hypothesis: “Feeling fearful about one’s health causes people to make healthier food choices.” Which type of research should Rosita choose to test this hypothesis...and why is this type of research the most appropriate tool? Experimental research...because the contexts in which people make food choices in the real world are constantly changing, and experimental research is the best tool for capturing what is happening in the culture right now. Experimental research...because her hypothesis states that there is a cause-and-effect relationship between fear and food choices, and experimental research is the best tool for testing whether one variable causes change in another. Correlational research...because her hypothesis states that there is a positive correlation between health-related fear and food choices, and correlational research would allow her to test that. Correlational research...because it would allow her to collect data on a broad range of people from all walks of life.
