The metal barium crystallizes in a body-centered cubic lattice. If the density of barium is 3.51g/cm3, what is the unit cell volume?
The enthalpy change for the reaction below at 25oC is -1,850 kJ (per mole of C9H20). What is the internal energy change for the reaction at 25oC
The flask was then shaken until the solution was uniform. A 25.0-mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution?
Compound A, C8H10, absorbed 3 equivalents of H2 on catalytic hydrogenation over a Pd/C catalyst to give B (C8H16). On ozonolysis, compound A gave, among other things, a ketone which was identified as cyclopentanone.
