Final answer:
The two substances likely to be associated with the vials are ethyl methylphenylglycidate, related to a strawberry fragrance, and phenol. These represent esters used in discussions of flavors and fragrances in chemistry and align with Dalton's postulate of conservation of mass during chemical reactions.
Step-by-step explanation:
The images described suggest an experimental setup involving chemical reactions. The first scenario with a liquid in a measuring cylinder and column apparatus could relate to distillation, a common method to separate or purify substances. The red dots scattered with concentrated areas might depict chromatography, a technique used to separate components of a mixture based on their different affinities to stationary and mobile phases.
From the information provided, the two substances that might have a connection with the vials are likely to include ethyl methylphenylglycidate, often associated with a strawberry fragrance and illustrated with hexagons and circles, and phenol, shown approximately two grams in a glass vial. These substances are used to exemplify esters often discussed in the context of flavors and fragrances in chemistry.
Moreover, the mention of Dalton's postulate could hint at a reaction where no atoms are destroyed, but rather redistributed. Esters like ethyl methylphenylglycidate are typically formed in reactions between alcohols and acids, aligning with Dalton’s principle of conservation of mass. The reference to C1V1 = C2V2 highlights the importance of concentration calculations in chemistry, potentially relevant to the vial contents.
