Sometimes the structure of phosphoric acid is written with single bonds to both the OH groups and to the oxygen atom; other times the bond between the P and the O is shown as a double bond. The "truth" probably lies somewhere between. Explain
How many moles of NaOH must be added to 0.550 L of 0.191 mol/L HC3H5O2(aq) to obtain a solution with pH=4.7. Assume the temperature is 25oC. (For HC3H5O2, pKa=4.89 at 25oC).
The arrangement of the orbitals is the same in a multielectron atom and a single-electron atom. In the Li atom, the 3s, 3p, and 3d orbitals have different energies. The He atom has one electron each in 1s and 2s orbitals.
