... antibonding MOs. There are two A1 SALCs and only one A1 AO (dz2), so we can form only three MOs of this symmetry. For simplicity, the scheme below assumes two bonding and one mixed antibonding MO. We do not have a B2 symmetry SALC, so the dxy AO on the metal will be nonbonding. Electron pairs from t ...

... the chloride ions in hydrochloric acid. It is used to estimate iron(II), hydrogen peroxide, ethanedioic (oxalic) acid and ethanedioate (oxalate) ions. The last two titrations are carried out above 60°C due to the slow rate of reaction. No indicator is required; the end point being the first sign of ...

Figure 4.12 suggests that NO3–(aq) might be reduced to any one of several products. We have no way at this point of predicting what ...
