You're trying to isolate limonene, an oil found in grapefruits which can be used to make medications. You will use TLC to determine if the compound you obtain is limonene. limonene To carry out the TLC, you will need to create a 2:3 hexanes:ethyl acetate eluting solvent. If you want a final volume of 10 mL of solvent, what volumes of hexanes and ethyl acetate would you need to add? (A) 2 mL ethyl acetate and 8 mL hexanes (B) 6 mL ethyl acetate and 4 mL hexanes (C) 3 mL ethyl acetate and 6 mL hexanes

3. Now that you know the physical state of each of the reactants and products in this chemical reaction lets think about what you might observe as the reaction is running. CH_3COOH(aq) + NaHCO_3(aq) → H_2O(l) + CO_2(g) + CH_3COONa(aq)   Upload a screenshot that shows how you performed all the calculations in Q3.
