Draw the structure of the organic compound that exists when lidocaine is in the presence of an acidic solution, for example, hydrochloric acid. You may use standard implicit style for atoms and lone-pairs if you like, but make sure that all bonds for what you do draw are explicitly visible (for example, give H-O-H not a condensed structure such as HOH or H2O).
Based on this equation, what is the value of the Rydberg constant (R) in m-1? (5 significant figures)
calculate mass of KHC8H4O4 (molar mass = 204.44 g/mol) that reacts with 15 ml of the NaOH solution
Aminabhavi et al. [T. M. Aminabhavi, V. B. Patil, M. I. Aralaguppi, J. D. Ortego and K. C. Hansen, J. Chem. Eng. Data 41, 526 (1996)] examined mixtures of cyclohexane with various long-chain alkanes.
The next items refer to the result of mixing 400. ml of 0.10 M NaOH and 100.0 mL of 0.10 M Mg(NO3)2. Reaction as shown goes essentially to completion.
The density of pure silver is 10.5 g/cm^3 at 20°C. If 4.63 g of pure silver pellets is added to a graduated cylinder containing 12.1 mL of water, to what volume level will the water in the cylinder rise.
How much energy is needed to heat 69.0 grams of H20(s) by 24.0 celcius if specific heat is 2.087 J(g celcius)
the pH of a neutral solution is 7.83. What is the value of Kw at that temperature?
Draw the major organic product from reaction of 1-butyne with NaNH2, then CH3Br. If no reaction occurs, write ethane, CH3CH3.
A solution is made by dissolving 25g of NaCl in enough water to make 1.00 L of solution. Assume that the density of the solution is 1.00 g/cm3. Calculate the mass percent, molarity, molality, and mole fraction of NaCl
Calculate the concentration of FeSCN^2+ after 25 mL of 0.002 M Iron nitrate Fe(NO3)3 is combined with 15.0 mL of 0.200 M
Calculate the spring constant of this silicone band including units. I know Hooke's law is F=-KX, where F is force, -K is the consent of the spring which I need to find and X is the displacement from relaxed position, but i'm giving the oscillatio..
What is the value of Ksp for Ag2SO4 if 5.54 g is soluble in 1.00 L of water?
