Write an equation for the rapid reaction (call this reaction 1) that occurs when aspirin (an acid) dissolves in sodium hydroxide (a base) solution.       Now write an equation for the slower reaction (reaction 2) between aspirin acetylsalicylic acid (an ester) and sodium hydroxide in the boiling water bath

Question: Comment on the solubility of the two dyes in water. In your answer consider intermolecular bonds and their relative strengths. Solubility of dye C: Solubility of dye D:

A student dissolved 4 drops of an unknown compound in 1 mL of methylene chloride (dichloromethane) in a test tube. They added 5 drops of a 2% solution of bromine in dichloromethane dropwise and mixed the contents within the test tube gently. They observed the red-brown color discharges (turns colorless) until the last drop. What compound is most likely the unknown? ©GMU 2020 Oa. Methanol b. Cyclohexane c. n-Butyl Bromide O d. Hex-2-ene COLE QUESTION 6 A student placed 2 drops of an unknown sample in a test tube and added 2 mL of ethanol to the test tube while mixing gently. They added 2 drops of potassium permanganate reagent to the test tube and mixed the contents of the test tube gently. The initial color was a deep purple but then changed to a yellow color which precipitates as a brown solid. What compound is most likely the unknown? OGMU 2020 a. Cyclopentane O b. Cyclohexene c. 1-Pentyl Chloride d. 2-Propanol SOUL QUESTION 7 A student performed the Beilstein test within a chemical…

Why is benzoic acid insoluble in water while sodium benzoate is soluble? How are their chemical structures related to their solubility? Which of them - benzoic acid or sodium benzoate - will be more soluble in CHCl3 and why?

Q9 9a: Rank the water solubility of the following compounds: H2N NH2 CH3-0-CH2CH3 H3C. H3C° NH2 TH. 9b: Certain C-H functional groups can form weak hydrogen bonds. Why would such a functional group be more likely to be a H-bond donor when the C (carbon) is next to N (nitrogen)? (explain in 2-3 sentences) 9c: Explain why water forms nearly spherical droplets on the surface of a freshly waxed car. Define the effect from your knowledge in biochemistry (explain in 2-3 sentences)

Draw and upload here as an attachment a molecular-level representation of ammonium chloride (NH4Cl) before the dissolution process occurs. Include a key to differentiate the ammonium cation (NH4*) and the chloride anion (Cl- ). (Remember, no .heic files!) Describe what forces are holding the particles in NH4Cl together.

A small amount of acetonitrile (CH,CN) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) D CH;CN H20 solution Use these sketches to answer the questions in the table below. The enthalpy of solution AH is negative when soln CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. O absorbed Would heat be absorbed or released if the system moved from Stage A to B? O released O neither absorbed nor released O none O ionic bonding force O covalent bonding force O metal bonding force O hydrogen-bonding force What force would oppose or favor the system moving from Stage A to B? Check all that apply. O dipole force O ion-dipole force O dispersion force

Blood is drawn from a patient to measure their “cholesterol levels.”  What is measured by this test the concentration of cholesterol in the blood the concentration of cholesterol in the liver the concentration of lipoproteins in the blood the concentration of all lipids in the blood  the first time i put the concentration of cholesterol in the blood because that's what the answers on here said, but I got it wrong
