In MgCl2, the oxidation state of Cl is -1 because it is a halogen. Since there are two Cl atoms, the total oxidation state contribution from Cl is -2. This means that the oxidation state of Mg is +2 in order to balance out the charges and form a neutral compound.
The oxidation state of Cl in HClO4 is +7. In HClO4, since the oxidation state of H is +1 and that of O is -2, the sum of the oxidation states in the compound must equal 0. Therefore, the oxidation state of Cl in this case is +7.
The oxidation state of Cl in HClO3 is +5. This is because the sum of the oxidation states in a neutral molecule must be zero, and since H has an oxidation state of +1, O has an oxidation state of -2, the oxidation state of Cl must be +5 in order to balance the charges.
The oxidation state of Cl in HCIO2 is +3. This is because hydrogen is typically assigned an oxidation state of +1 and oxygen is typically assigned an oxidation state of -2, so the sum of the oxidation states in HClO2 must equal the charge of the ion, which is 0 in this case.
The oxidation number of Sodium in the Na + ion = 1
Chlorine shows many numbers. It dhows +3 in here.
The oxidation state of Cl in HClO3 is +5. Each hydrogen has an oxidation state of +1, and oxygen has an oxidation state of -2, which gives chlorine an oxidation state of +5 to balance the overall charge of the molecule.
The oxidation state of Cl in HClO4 is +7. In HClO4, since the oxidation state of H is +1 and that of O is -2, the sum of the oxidation states in the compound must equal 0. Therefore, the oxidation state of Cl in this case is +7.
The oxidation state of Cl in HClO3 is +5. This is because the sum of the oxidation states in a neutral molecule must be zero, and since H has an oxidation state of +1, O has an oxidation state of -2, the oxidation state of Cl must be +5 in order to balance the charges.

Magnesium chloride is a salt.
This compound is magnesium chloride.
The oxidation state of Cl in HCIO2 is +3. This is because hydrogen is typically assigned an oxidation state of +1 and oxygen is typically assigned an oxidation state of -2, so the sum of the oxidation states in HClO2 must equal the charge of the ion, which is 0 in this case.
The oxidation number of Sodium in the Na + ion = 1
I didn't know there was an element called Ci?? I presume u meant Cl (CL) Chlorine It is 0 if it exist as a free element. (Which means that it is 0 if is not chemically combined to anything) But if it is in a compound, it is usually -1 (minus one) e.g HCl (The oxidation state of Cl in HCl is -1 (negative one) But in ZnCl2 (The oxidation state of Cl is still -1 BUT there is two chlorine atoms inside the compound, so it is -1 x(times/multiply) 2 = which is -2. The oxidation state in ZnCl2 is -2)

Magnesium Chloride - MgCI2
The chemical reaction shown is a single displacement reaction, where magnesium (Mg) displaces hydrogen (H) in hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2).
