**Matching Samples to Designations:**Match the four samples below to their correct designation (either pure substances or mixtures):1. **R-(−)-Carvone** - Options: - A. Pure substance - B. Mixture2. **Spearmint oil** - Options: - A. Pure substance - B. Mixture3. **S-(+)-Carvone** - Options: - A. Pure substance - B. Mixture4. **Caraway oil** - Options: - A. Pure substance - B. Mixture**Explanation:**- **Pure substances** are samples that contain only one type of molecule or atom. Examples include elements and compounds with a consistent, definite composition. - **Mixtures** are combinations of two or more substances where each retains its own properties and can be physically separated. They do not have a fixed composition.

Concepts: a organic compound is pure in it has a only perticular enantiomer present. In there is…

Create a Schematic Diagram Delivering an aliquot and dilution1. Using a serological pipette, transfer accurately a 10-ml aliquot of the previously prepared NaCl solution into a 100-ml volumetric flask, then dilute to mark using distilled water.2. Put a stopper on the volumetric flask. Then invert the glassware up and down around five times, making sure there are no leaks.3. Put the diluted solution in a reagent bottle, then properly label the solution. Note the concentration of the solution. Show your reagent bottle to your instructor for checking.
