In most chemical environments, Pb (II) is more stable than Pb (IV). Therefore, Pb (IV) compounds will often extract electrons from other materials to form a Pb (II) compound instead.

Various methods used for purification and separation of organic compounds are: i) Crystallisation ii) Fractional Crystallisation iii) Sublimation iv) Distillation v) Extraction with solvents vi) Chromatography.
Titanium is a tetravalent metal and donates four electrons to form titanium (IV) ions (Ti4+). It therefore forms ionic compounds, which include titanium carbide (TiC), titanium dioxide (TiO2) and titanium (IV) chloride (TiCl4).
No. Carbon is an element and on its own isn't organic.
Lead has two oxidation states (+4 and +2). As a result, there are two compounds composed of lead and sulfate: lead(IV) sulfate, which is Pb(SO4)2, and lead(II) sulfate, which is PbSO4.
Lead(IV) iodide, or PbI4 is unknown and not present, because Iodine is not that much strong oxidizer to oxidize Lead or Lead(II) ions to Lead(IV) ions. However, Oxygen and Fluorine have this oxidizing power, and thus forming compounds of Lead(IV).

no he made silly decisions
it results to the formation of sulphur (iv) oxide which is poisonous
The formula for the compounds: Chromium (VI) Phosphate; Vanadium (IV) Carbonate; Tin (II) Nitrite?
PbCl2 is lead(II) chloride, PbCl4 is lead(IV) chloride
The world is leveled so eventually around level 18+ the most powerful weapons appear on enemies and in stores.
Disregarding Legendaries, the most powerful Pokemon by stats is Slaking. Although Nature and IV's also have a lot to do with it. It all depends on the stats you like.

Diazepam is available in injectable form. Theoretically, the diazepam, in pills, could be separated from the binding agents and injected. Practically, this is beyond the capabilities of most users and injecting the binding agents may have adverse effects. In any case, injecting diazepam should only be done when there's no alternative as tolerance and/or dependence are likely to develop more quickly than with oral administration. If the IV use is intended to decrease the time to onset of effect, sub-lingual would be preferable. If the IV use is for "recreation", treatment would be preferable.
