complete the following table: some polyatomic ions name chemical formula po₄³⁻ no₃⁻ cn⁻ h₃o⁺
Answer
Explanation:
Step1: Recall poly - atomic ion names
The ion $PO_{4}^{3 - }$ is called phosphate ion.
Step2: Recall another ion name
The ion $NO_{3}^{-}$ is called nitrate ion.
Step3: Recall more ion names
The ion $CN^{-}$ is called cyanide ion.
Step4: Recall the last ion name
The ion $H_{3}O^{+}$ is called hydronium ion.
Answer:
| name | chemical formula |
|---|---|
| phosphate ion | $PO_{4}^{3 - }$ |
| nitrate ion | $NO_{3}^{-}$ |
| cyanide ion | $CN^{-}$ |
| hydronium ion | $H_{3}O^{+}$ |
