### 3. Names of Ionic Compounds

\begin{tabular}{|l|l|}
\hline
[tex]$CaSO _4$[/tex] & Calcium sulfate \\
\hline
[tex]$\left(AlNO _3\right)_3$[/tex] & \\
\hline
[tex]$Na _2 CO _3$[/tex] & \\
\hline
[tex]$MgSO _3$[/tex] & \\
\hline
[tex]$Cu ( OH )_2$[/tex] & \\
\hline
[tex]$Mg _3\left( PO _4\right)_2$[/tex] & \\
\hline
\end{tabular}

Fill in the missing names for the following ionic compounds.



Answer :

Absolutely, let's fill in the names of the ionic compounds in the table in a step-by-step manner.

Initially, the table given is:
```
\begin{tabular}{|l|l|}
\hline [tex]$CaSO _4$[/tex] & Calcium sulfate \\
\hline [tex]$\left.AlNO _3\right)_3$[/tex] & \\
\hline [tex]$Na _2 CO _3$[/tex] & \\
\hline [tex]$MgSO _3$[/tex] & \\
\hline [tex]$Cu ( OH )_2$[/tex] & \\
\hline [tex]$Mg _3\left( PO _4\right)_2$[/tex] & \\
\hline
\end{tabular}
```

Here are the names of the compounds:

1. For [tex]\(CaSO_4\)[/tex], the name is Calcium sulfate.
2. For [tex]\(Al(NO_3)_3\)[/tex], the name is Aluminum nitrate.
3. For [tex]\(Na_2CO_3\)[/tex], the name is Sodium carbonate.
4. For [tex]\(MgSO_3\)[/tex], the name is Magnesium sulfite.
5. For [tex]\(Cu(OH)_2\)[/tex], the name is Copper(II) hydroxide.
6. For [tex]\(Mg_3(PO_4)_2\)[/tex], the name is Magnesium phosphate.

Now, let's fill in these names into the given table:

[tex]\[ \begin{tabular}{|l|l|} \hline $CaSO_4$ & Calcium sulfate \\ \hline $Al(NO_3)_3$ & Aluminum nitrate \\ \hline $Na_2CO_3$ & Sodium carbonate \\ \hline $MgSO_3$ & Magnesium sulfite \\ \hline $Cu(OH)_2$ & Copper(II) hydroxide \\ \hline $Mg_3(PO_4)_2$ & Magnesium phosphate \\ \hline \end{tabular} \][/tex]

Now, the table is fully completed with all the names of the ionic compounds.
