Question- Draw a hydrogen bond between two urea molecules. Be sure to clearly represent the important aspects of the structure of each molecule in your drawing and clearly identify the donor atom (D) and the acceptor atom (A) in your hydrogen bond. On your drawing, identify the location and an expected numerical value for each of the following angles (note that dashed lines indicate interactions BETWEEN the two molecules): X-A----H and A-----H-D Explain your reasoning for the values for the bond angles that you gave in part b.
Please express all work. Thank you in advance
What is the molar solubility of AgCl in water. For AgCl, Ksp=1.8 x 10-10. Give your answer in moles per litre, accurate to two significant figures
Presume you desire to prepare an acetic buffer at pH = 3.95 by adding 0.200 M KOH to 200.00mL of 0.300 M acetic acid CH3COOH. Explain how much volume of the base do you need in order to prepare such a buffer solution
What is the significance of high pressure used in HPLC?
Draw a glycerophospholipid made up of the components glycerol, phosphoric acid, choline, linoleic acid, and linolenic acid.
a calorimeter containing 200.0 ml of water was calibrated by carrying out a reaction which released 15.6 kj of heat. if
Assume you dissolve .378 g of the weak acid benzoic acid in enough water to make 1.00e2 ml of solution and then titrate the solution with .200 M NaOH.
A bomb calorimeter has a heat capacity of 2.47 kJ/K. While a 0.105 g sample of ethylene (C2H4) was burned in this calorimeter, the temperature increased by 2.14K. Compute the energy of combustion for one mole of ethylene.
