The oxidation state of chlorine is 5.
+5
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.
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 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.
it is an acid
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.

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)
it is an acid
Chlorine shows many numbers. It dhows +3 in here.
HCIO2 is "chlorous acid"
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The oxidation state of calcium is +2.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
