Give the reaction scheme, showing the products formed (before hydrolysis), when one equivalent of ethylmagnesium bromide is treated with one equivalent of 5-hydroxy-2-pentanone. Does the addition of two equivalents of the Grignard reagent to this, y...
If 3-bromo-1-propanol is treated with NaOH, a compound of molecular formula C3H6O is formed. Suggest a structure for this product.
You may wish to review the Laws of Thermochemistry and Endothermic and Exothermic Reactions before you begin. A table of single bond energies should be used as a help (available in most general chemistry text books). Estimate the change in enthalp...
Tables are available for heats of formation of common compounds and ions in aqueous solution in most general chemistry textbooks. Calculate DH for the following reaction: 8 Al(s) + 3 Fe3O4(s) --> 4 Al2O3(s) + 9 Fe(s)
Reduction through constant current electrolysis a) How much Cr3+ was reduced to Cr2+? b) A few seconds after the electrolysis was stopped, the potential of the cell came to rest at -0.524 volts. How much Cr3+ actually remains in the solution? c) ...
When VO2+ reacts with Ti2+ in acid solution the products are V2+ and TiO2+. a) What is the potential of the cell Pt/VO2+, V2+//TiO2+, Ti2+/Pt if all species are a 1 M. b) Write the equilibrium constant expression and calculate the value of the equi...
An ideal solution with solute density 1.05 and solvent density 1.00 is subject to a huge gravity force field, a linear function of postition, F=kr, k is a constant and r is the position along the field. Derive the concentration as a function of T an...
