chart with columns: chemical name, chemical formula, chemical name, chemical formula; rows include acetate (c₂h₃o₂⁻), carbonate (co₃²⁻), hypocarbonite (co₂⁻), hydrogen carbonate (bicarbonate) (hco₃⁻), chlorite (clo₂⁻), hypochlorite (clo⁻), chlorate (clo₃⁻), nitrite (no₂⁻), ammonium (nh₄⁺), cyanide (cn⁻), hydroxide (oh⁻), peroxide (o₂²⁻), phosphate (po₄³⁻), hydrogen phosphate (hpo₄²⁻)

Explanation:

Para determinar el nombre del compuesto \( \text{KCN} \), primero identificamos los iones. El cation es \( \text{K}^+ \) (potasio) y el anión es \( \text{CN}^- \). De la tabla, el ion \( \text{CN}^- \) se llama cianuro. Entonces, el compuesto se nombra como potasio cianuro.

Answer:

D. potassium cyanide
