Question

Criss cross method of Hydrogen peroxide

Answer 1

this is criss cross method , hope it will be useful for u

Answer 2

Explanation:

• We already know that the criss-cross approach can be used to write chemical formulas.
• The numerical value of the ion charge of the two atoms is crossed across in the criss-cross method, which forms the subscript of the other ion.
• The Thorpe's Crisscross method is a technique for determining the chemical formulas of metals and non-metals that create an ionic bond.
• The absolute value of the first ion's oxidation number is employed as the subscript of the second, and vice versa, in this procedure.
• The greatest common factor is then used to reduce the subscripts.
• Given that you're enquiring about the Criss-cross valency approach.
• Oxidation state of oxygen atom in H2O2 is 02^2- = -1. & Hydrogen atom oxidation state in H+ =+1
• The peroxide ion is 02^2- because there is a proxy relationship.

As a result, 2H+ ions are required to balance the charge.

Or we can say that in criss cross method :

2+ —> O2

2- —-> H2

Therefore the valency of O2 in oxygen molecule is 2.and the valency of H2 is to be seen as -2. Hence by criss cross method, we get the final formula as H2O2.
