A. Ketamine is an analgesic that has moved onto the street as a result of its hallucinogenic properties. How does ketamine interact with water molecules? (show structures) B. Clinically, ketamine is typically stored prior to dilution for injection in a stock solution containing 100 mg/mL ketamine hydrochloride at pH 6.8. Given a molecular weight of 274.18 g/mol and a pKa of 7.5, determine the concentration of ketamine that is found in its hydrochloride form and the concentration in the free...

Water has significant IMF, which result in many of its unique properties—high boiling point relative to its molecular weight, high surface tension, strong capillary action. Draw the molecular structures for six water molecules and show how they might organize themselves due to hydrogen-bonding. Show the H-bonds with dotted lines.

During laser vision correction, a brief burst of 193 nm ultraviolet light is projected onto the cornea of the patient. It makes a spot 1.50 mm in diameter and deposits 0.445 mJ of energy. Calculate the depth (in µm) of the layer ablated, assuming the corneal tissue has the same properties as water and is initially at 34.0°C. The tissue's temperature is increased to 100°C and evaporated without further temperature increase. (The heat capacity of water is 4,186 J/(kg ·...

The process of DNA replication involves a variety of enzymes that interact in complicated ways. Not frames in a film represent different stages in its progression. 1. Suppose that a replication fork has been initiated and is moving to the right. Draw a diagram illustrating the template molecules and the newly synthesized molecules at a particular moment in time. Be sure to differentiate between these two types of molecules as well as between deoxyribo- and ribonucleic acids. Be sure also...

Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water: C6H5COOH⇌C6H5COO−+H+ The pKa of this reaction is 4.2. In a 0.76 M solution of benzoic acid, what percentage of the molecules are ionized? Express the percentage numerically using two significant figures.
