Question

1. name the following ion: o2- (0.5 points) *

enter your answer

1. name the following ion: cl- (0.5 points) *

enter your answer

1. name the following compound: nh4oh (0.5 points) *

enter your answer

Explanation:

• For \(O^{2 -}\): The element is oxygen. When naming anions, we change the ending of the element name to -ide. So, \(O^{2 -}\) is called oxide ion.
• For \(Cl^{-}\): The element is chlorine. Using the rule for naming anions (change the ending to -ide), \(Cl^{-}\) is called chloride ion.
• For \(NH_4OH\): \(NH_4^{+}\) is the ammonium cation and \(OH^{-}\) is the hydroxide anion. When naming ionic compounds, we name the cation first followed by the anion. So, \(NH_4OH\) is called ammonium hydroxide.

Answer:

1. Oxide ion
2. Chloride ion
3. Ammonium hydroxide
