Answer 1

The chemicals (HF, Ar, CsCl, and HCl) are assigned to the four beakers based on their normal boiling points, resulting in CsCl in beaker B, HF in beaker D, HCl in beaker A, and Ar in beaker C.

Step-by-step explanation:

Given four beakers A, B, C, and D containing unlabeled chemicals and their boiling points in the order B>D>A>C, we need to assign HF (Hydrogen Fluoride), Ar (Argon), CsCl (Cesium Chloride), and HCl (Hydrochloric Acid) to their respective beakers based on their boiling points. The boiling points of these substances are as follows: HF boils at 19.5 °C, HCl at -85.05 °C, Ar at -185.85 °C, and CsCl at a much higher temperature since it is a salt, typically around 1413 °C. Based on this, the order of chemicals from the highest to lowest boiling point is CsCl, HF, HCl, Ar, which corresponds to beakers B, D, A, C respectively.

The ordering would then be:

• Beaker B: CsCl (Cesium Chloride)
• Beaker D: HF (Hydrogen Fluoride)
• Beaker A: HCl (Hydrochloric Acid)
• Beaker C: Ar (Argon)
