The continuous process for removing mercury comprises a step of continuously feeding a mercury-containing liquid hydrocarbon to an ionization zone where the elementary mercury is ionized; and a step of continuously feeding the liquid hydrocarbon containing the ionized mercury to a sulfur compound-...
In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. The most electronegative a...

The continuous process for removing mercury comprises a step of continuously feeding a mercury-containing liquid hydrocarbon to an ionization zone where the elementary mercury is ionized; and a step of continuously feeding the liquid hydrocarbon containing the ionized mercury to a sulfur compound-treatmen...
[1]. There are two types of efflux systems: protein systems that transport a specific toxic compound or class of toxins from cell, which export numerous structurally dissimilar compounds [2]; the latter type of transporter is involved in the export of a wide range of antimicrobial compounds, ...
For example, the compound mercuric oxide can be broken down by heating into two other substances: 2 HgO → 2 Hg + O2 ... but the two products, metallic mercury and dioxygen, cannot be decomposed into simpler substances, so they must be elements. The definition of an element given above ...
What characteristic distinguishes element from compound? a) Define the nephelauxetic effect. b) Briefly discuss the trends in the nephelauxetic series of ligands in terms of the covalent character of complexes and the softness of ligands. Use atomic or molec...
