Calculate (a) the mean potential energy and (b) the mean kinetic energy of an electron in the ground state of a hydrogenic atom
What are the resonance structures for [H2CNO2]-? The problem asks for the major and minor contributors. The answer key says that there are two structures in which the only double bond switches between the two NO bonds
Calculate the number of moles of cytochrome c3+ (Fe3+) formed from cytochrome c2+ (Fe2+) with the Gibbs energy derived from the oxidation of 1 mole of glucose
The pKa of benzoic acid is 4.2, whereas that of carbonic acid, H2CO3, is 6.4. On the basis of this information, would aqueous sodium bicarbonate be sufficiently basic to deprotonate benzoic acid? Explain your reasoning.
Consider the following reaction. N2 + 3H2 -> 2NH3 . 28.0 grams of N2 and 5.04 grams of H2 are reacted, producing 17.8 grams of NH3. What is the percent yield?
