Hgnh2cl
Mercury's most common oxidation state is +2
Oxidation state of any element in its elemental state is 0
Zinc commonly exists in compounds in the +2 oxidation state only, and as a metal with an oxidation state of 0.0, 1 and 2 oxidation states
The oxidation state of Hg in Hg2Cl2 is +1.It has +1 state.
For the one oxidation state. HgNO3 for the two oxidation state. Hg(NO3)2
When in the 1+ oxidation state, mercury does not occur as a lone Hg+ ion. Instead it forms the polyatomic ion Hg22+. As a result, this ion will bond with two bromide (Br-) ions.
Hg2O.
Mercury do not occur in combine state (i.e. it occur in free state) and in liquid form. It is the only metal who occur in liquid form.
Mercury only has a two and one oxidation state. HgO would be the formula for mercury II oxide.
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
-2 oxidation state
The final oxidation state of calcium after a reaction depends on the specific reaction and compounds involved. Calcium commonly forms a +2 oxidation state by losing two electrons. However, it can also form other oxidation states, such as +1 in certain compounds or complexes. To determine the final oxidation state after a reaction, one must consider the rules of oxidation states and analyze the compound formed.
