When 20.0 grams of water is cooled from 20.0 Celsius to 10.0 Celsius, the number of Joules of heat released is
A copper, Cu(s), electrode is immersed in a solution that is 1.00 M in ammonia, NH3, and 1.00 M in tetraamminecopper(II), [Cu(NH_3)_4]^{2+}. If a standard hydrogen electrode is used as the cathode, the cell potential, E_cell, is found to be 0.076 ..
Hydrogenation of carbon double bonds C=C (i.e. adding a hydrogen on each carbon atom and thus reducing the double bond into a single bond: H-C-C-H) is a very common process in organic and polymer chemistry.
Draw one planar structure each for the following compounds using dashed or solid wedges to show the stereochemistry of the substituent groups. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons).
Determine the empirical formula of estradiol. The molecular weight of estradiol was later determined to be 272. Determine the molecular formula of estradiol.
