Chlorine shows many numbers. It dhows +3 in here.
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 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 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 calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
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.
In hypochlorous acid (HClO2), the oxidation state of chlorine (Cl) can be determined by considering the oxidation states of the other atoms. Hydrogen (H) has an oxidation state of +1, and each oxygen (O) has an oxidation state of -2. The overall charge of the molecule is neutral, so we can set up the equation: +1 + x + 2(-2) = 0. Solving for x gives an oxidation state of +3 for chlorine in HClO2.
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 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 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.
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)
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.
2 oxidation state
O = -2 oxidation state H = +1 oxidation state
