According to the official answer key, PbO isn't ionic. Although I know this distinction between ionic and covalent isn't defined sharply. But Pb is a metal and Oxygen is a non-metal.

Pyrrole is weakly basic, with a conjugate acid pKa of −3.8. The most thermodynamically stable pyrrolium cation (C4H6N+) is formed by protonation at the 2 position. Substitution of pyrrole with alkyl substituents provides a more basic molecule—for example, tetramethylpyrrole has a conjugate acid pKa of +3.7.

P value is constant for a given metal ion. Finally, ammonia is weak field ligand but in certain cases, it acts as a strong field ligand (example: for Cobalt). For Fe, ammonia is a weak field ligand. Hence no pairing takes place.

So according to me, it should be Ionic. I tried to find on the internet I couldn't able to find out about PbO, although PbO2 is defined in between of ionic and covalent according to this paper. PbO should be more ionic than PbO2 since oxidation state of the Pb is lower, it will be less electronegative.

Identify the oxidation and reduction reactions By convention in standard cell notation, the anode is written on the left and the cathode is written on the right. So, in this cell: Zinc is the anode (solid zinc is oxidised). Silver is the cathode (silver ions are reduced).

Color: Gold and pyrite both have a brilliant metallic luster, but are different tones of yellow. Gold is golden to silvery yellow, whereas pyrite is a pale to medium brassy yellow that sometimes tarnishes. ... Pyrite can also occur as shapeless grains.

optical isomerism Here, aa represents bidentate ligand, x or y represents monodentate ligand and M represents central metal ion. Hence, [Co(NH3)3Cl3]0 due to presence of symmetry elements does not exhibit optical isomerism.

Yes, there are differences between the colour systems. ... TPG colours and TPX colours are the same, but the new TPG suffix indicates much more eco-friendly formulations.

Pyrite is included on lists of toxic minerals because it might contain small amounts of arsenic. Yes, pyrite can contain some arsenic, but since pyrite is not soluble in water or hydrochloric acid it poses no risks when handled.

They are the same, E- ≡ trans- and Z- ≡ cis- . Except E-Z is used for more complex isomers. As each side only has 1 H and 1 Cl atom, you can tell if the Cl atoms are on the same or opposite sides, and therefore decide upon cis- or trans-.

Since anilines are prepared from nitro compounds, some azo dyes are produced by partial reduction of aromatic nitro compounds. Many azo dyes are produced by reactions from pre-existing azo compounds. Typical reactions include metal complexation and acylation.
