4. There are two Hg's and two Cls.
The formula for mercurous chloride (Hg2Cl2). It is also called mercury(I) chloride.
Mercury(I) chloride, Hg2Cl2, is written with the subscripts 2 because there are 2 mercury atoms and 2 chloride ions in each molecule. Writing it as 2HgCl would imply that there are 2 mercury atoms but only 1 chloride ion, which is incorrect based on the actual chemical composition of the compound.
The molecular formula of HgCl would be HgCl2. The molar mass of HgCl2 is approximately 472.2 g/mol, which corresponds to one mercury atom (Hg) and two chlorine atoms (Cl) in each molecule of mercury(II) chloride.
In H2C2O4, oxidations states are +3 for Mn in Mn2O7, +2 for Hg in Hg2Cl2, and +5 for I in IF5.
The oxidation number of Hg in Hg2Cl2 is +1. This is because each Chlorine atom in Hg2Cl2 has an oxidation number of -1 and the overall molecule is neutral. Thus, the oxidation number of Hg can be calculated as follows: 2x + 2(-1) = 0, which gives x = +1.

Hg2Cl2
A single mercurous ion has two positive charges and contains two mercury atoms and therefore has the formula Hg2+2. This cation requires two chloride anions, each which has a single negative charge, for the electroneutrality required in a compound between them, resulting in the formula given.
The molecular formula of HgCl would be HgCl2. The molar mass of HgCl2 is approximately 472.2 g/mol, which corresponds to one mercury atom (Hg) and two chlorine atoms (Cl) in each molecule of mercury(II) chloride.
The oxidation state of Hg in Hg2Cl2 is +1.It has +1 state.
The chemical formula for calomel is Hg2Cl2, where Hg represents mercury and Cl represents chlorine.
Hg2Cl2.
The ratio of atoms in mercurous chloride (Hg2Cl2) is 2:2:2, as there are two atoms of mercury (Hg) and two atoms of chlorine (Cl) in each molecule of mercurous chloride. This means the ratio of mercury to chlorine atoms in mercurous chloride is 1:1.
In H2C2O4, oxidations states are +3 for Mn in Mn2O7, +2 for Hg in Hg2Cl2, and +5 for I in IF5.
Formula: Hg2Cl2
The oxidation number of Hg in Hg2Cl2 is +1. This is because each Chlorine atom in Hg2Cl2 has an oxidation number of -1 and the overall molecule is neutral. Thus, the oxidation number of Hg can be calculated as follows: 2x + 2(-1) = 0, which gives x = +1.
