Calculate the binding energy per nucleon for 21H and 31H. The atomic masses are 21H, 2.01410 amu, and 31H, 3.01605 amu.
What is the molar composition of the vapor in equilibrium with a boiling liquid that has a composition of 60% A and 40% B
what is the molarity of HCl in a solution prepaired by dissolving 18.25 gm HCl in 200 gm ethanol, if the density of solution is 0.86 gm per mm
Calculate the distance NH3 gas and HCl gas would travel if a 100.0-cm tube were used, based on the accepted molar mass of the two gases
This precipitate is removed and excess H SO is then added to the solution which forms a precipitate. This precipitate is removed and excess NaOH is added to the supernatant until the solution is strongly basic. The addition of the NaOH does not pr..
Regarding the reaction of the products that correspond to syn addition of Br2 to trans cinnamic acid and those that correspond to anti addition, why would you isolate a pair of enantiomers rather than a single enantiomer from this reaction
