Question- Draw the most stable conformoer of (2S,3R)-3-BROMO-2-Iodobutane in both a line drawing with wedge/hash sterochemical information and as a newman projection. Place carbon 2 in the front in the newman projection
Please show me how work it out above problem
4.60 mol of solid A wasplaces in a sealed 1.00 L container and allowed to decompose into gaseous B and C. The concentration of B steadily increased until it reached 1.10M where it remained constant.
how do you calculate the density of metals? could this method be used for determining the density of mercury as well?
Using the following data, calculate the concentration of copper(II) ions in the unknown solution. The cell path length is 1.00cm in all cases , and the wavelength used in the determination was 645nm.
the wavelength of the emitted photon corresponds to the difference in energy between the two energy levels. What were the principal quantum numbers of the initial and intermediate excited states involved?
commercial concentrated aqueous ammonia is a solution of 28.0%, by mass, ammonia, NH3, (molar mass=17.0 g/mol) in water. the density pf the solution is .900g/mL.
A semipermeable membrane is placed between the following solutions. Which solution will decrease in volume? Solution A: 1.31% (m/v) starch Solution B: 7.48% (m/v) starch
