Question

What do the formulas for table salt, NaCl, and water, H2O indicate about the compounds

Answer 1

The formulas for NaCl and H2O indicate the composition and ratio of the elements in the compounds.

Step-by-step explanation:

The formulas for table salt, NaCl, and water, H2O, indicate the composition and ratio of the elements in the compounds.

NaCl: NaCl is an ionic compound composed of sodium cations (Na+) and chloride anions (Cl-) in a 1:1 ratio. It represents a formula unit of table salt.

H2O: H2O is a molecular formula for water. It indicates that water is composed of two hydrogen atoms (H) bonded to one oxygen atom (O) in a 2:1 ratio.

Answer 2

The formulae for these elements indicate that the compounds are made up of two elements. In the case of table salt, this is sodium (Na) and chlorine (Cl). For water, the two elements are hydrogen (H) and oxygen (O).
