The mole ratio of species in a chemical reaction

Answer 1

Answer: The mole ratio of atoms or ions in the compound

Step-by-step explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water with chemicl formula
`H_2O`

The subscript 2 in
`H_2O` represents that the ratio of hydrogen atom is twice that of oxygen atom.

Thus SUBSCRIPTS in a compound represent the mole ratio of atoms or ions in the compound
