Question

the possible charge(s) of the pb (lead) ion is (are):
+2
+1, +3, +4
+2, +3, +4
+2, +4
+1, +3

question 4
1 pts
name the following ions:
cro₄²⁻ is the ion
clo₄⁻ is the ion
mno₄⁻ is the ion
oh⁻ is the ion

Explanation:

Step1: Recall lead ion charges

Lead (Pb) commonly forms ions with charges of +2 and +4 due to its electron - configuration and tendency to lose electrons in chemical reactions.

Step2: Analyze ion naming for Question 4

• For $CrO_4^{2 - }$, it is called chromate ion as it is a common poly - atomic ion with this name.
• For $ClO_4^{-}$, it is the perchlorate ion. The naming convention for oxo - anions of chlorine has $ClO_4^{-}$ as perchlorate.
• For $MnO_4^{-}$, it is the permanganate ion.
• For $OH^{-}$, it is the hydroxide ion.

Answer:

The possible charge(s) of the Pb (lead) ion is (are): +2, +4
$CrO_4^{2 - }$ is the chromate ion
$ClO_4^{-}$ is the perchlorate ion
$MnO_4^{-}$ is the permanganate ion
$OH^{-}$ is the hydroxide ion
