Question

the chemical formula of water is... (with an image of a water molecule labeled oxygen and two hydrogens; options: h₂o, ho₂, h₃o, ho)

Explanation:

Water is a compound made up of two hydrogen atoms and one oxygen atom. The chemical formula representing this composition is \(H_2O\), where the subscript 2 indicates two hydrogen atoms bonded to one oxygen atom. The other options (\(HO_2\), \(H_3O\), \(HO\)) do not correctly represent the atomic ratio in a water molecule.

Answer:

A. \(H_2O\)
