CH2O=1+2+1=4

Answer 2

Sum of Indexes in Chemical Formula

To find the sum of the indexes in the chemical formula CuCl2H3PO4Al2S3CH2O, we need to add up the subscripts (indexes) of each element in the formula.

The chemical formula provided contains the following elements and their respective subscripts: - Cu (Copper) with a subscript of 1 - Cl (Chlorine) with a subscript of 2 - H (Hydrogen) with a subscript of 3 - P (Phosphorus) with a subscript of 1 - O (Oxygen) with a subscript of 1 - Al (Aluminum) with a subscript of 2 - S (Sulfur) with a subscript of 3

To calculate the sum of the indexes, we simply add up the subscripts for each element: 1 + 2 + 3 + 1 + 1 + 2 + 3 = 13

So, the sum of the indexes in the chemical formula CuCl2H3PO4Al2S3CH2O is 13.
