Question

name the following compound
nano3

question 2

name the following compound
mnpo4

Explanation:

For \( \text{NaNO}_3 \):

• \( \text{Na}^+ \) is the sodium ion.
• \( \text{NO}_3^- \) is the nitrate ion.
• When naming ionic compounds, we name the cation first followed by the anion.

For \( \text{MnPO}_4 \):

• \( \text{PO}_4^{3-} \) is the phosphate ion.
• Manganese (\( \text{Mn} \)) can have multiple oxidation states.
• Since phosphate has a charge of \( -3 \), manganese must have a charge of \( +3 \) to balance the compound.
• We use Roman numerals in parentheses to indicate the oxidation state of the metal in the name.

Answer:

1. Sodium nitrate
2. Manganese(III) phosphate
