Solution Steps

Step 1: Identify the missing chemical formula for acetate anion

The acetate anion is a common polyatomic ion with the chemical formula \(\mathrm{C_2H_3O_2^-}\).

Step 2: Identify the name of the ion with the formula \(\mathrm{NH_4^+}\)

The ion with the chemical formula \(\mathrm{NH_4^+}\) is known as the ammonium ion.

Step 3: Identify the name of the ion with the formula \(\mathrm{ClO_3^-}\)

The ion with the chemical formula \(\mathrm{ClO_3^-}\) is known as the chlorate ion.

Final Answer

  • Acetate anion: \(\boxed{\mathrm{C_2H_3O_2^-}}\)
  • \(\mathrm{NH_4^+}\): \(\boxed{\text{ammonium ion}}\)
  • \(\mathrm{ClO_3^-}\): \(\boxed{\text{chlorate ion}}\)
