The number of ions in a compound depends on the structure of the compound and the oxidation states of the elements within the compound. An element's oxidation state is the number of electrons that an atom possesses or lacks relative to the number of protons in its nucleus. This determines t...
The oxidation state of an element describes the number of electrons transferred in reactions. For example, the oxidation or valence states of the following elements are equal to the number of equivalents: • Calcium: Ca+2 ion: valence of 2: number or no. of equivalents: 2 • Aluminum: ...
1. The oxidation number of an element in its free state is zero. Example: The oxidation number of Zn, Al, H2, O2, and Cl2 is zero 2. The oxidation number of a monatomic ion is the same as the charge on the ion. Example: The oxidation number of Na+ is +1, Mg2+ is +2, Al...
Explain how to find the oxidation numbers for Zn+HCl→ZnCl2+H2. Displacement Reaction:In this example of a single-displacement reaction, the lone element (zinc) displaces the on of the ions on a salt (hydrogen cation) to form a new salt and an independent element of t...
How can one find the valency of an element? How do you find the valency of an element? How do you write a net ionic equation of the products KI and Pb(NO_3)_2? What are some tips on how to do stoichiometry? CIO^-+ 2I^-+ 2H^+CI^-+ I_2+ H_2O Explain clearly using equat...
However, the nature of oxidation, metal dissolution, and interface reactions between the oxide film and the metal surface and all the element-specific effects remain elusive. The reason is that the underlying mechanisms are hidden in the nanoscale, and the atomic configurations and partitioning ...
So what's the fourth state of matter? How to Create Plasma Gas The amount of heat (which translates to the amount of energy) applied to water molecules determines their behavior and therefore their state. Simply put, more heat (more energy) excites molecules to the point that they break fr...
