To solve the problem of naming the ionic compounds listed in the practice sheet, we need to follow the rules for naming ionic compounds. Here's a step-by-step explanation and the solutions:
Rules for Naming Ionic Compounds:
1.
Binary Ionic Compounds (Metal + Nonmetal):
- The metal is named first.
- The nonmetal ends with "-ide."
- If the metal can form multiple ions (e.g., iron), use Roman numerals to specify the charge.
2.
Polyatomic Ions:
- Recognize common polyatomic ions (e.g., sulfate, nitrate, hydroxide).
- Name the cation first, then the anion.
3.
Transition Metals:
- Use Roman numerals to indicate the charge of the transition metal ion.
4.
Ammonium Ion:
- Ammonium is always written as "ammonium."
5.
Acids:
- Not directly relevant here, but acids are named based on their anions.
Solutions:
1.
Na₂CO₃
- Sodium carbonate
2.
NaOH
- Sodium hydroxide
3.
MgBr₂
- Magnesium bromide
4.
KCl
- Potassium chloride
5.
FeCl₂
- Iron(II) chloride
6.
FeCl₃
- Iron(III) chloride
7.
Zn(OH)₂
- Zinc hydroxide
8.
Be₃SO₄
- Beryllium sulfate
9.
CrF₂
- Chromium(II) fluoride
10.
Al₂S₃
- Aluminum sulfide
11.
PbO
- Lead(II) oxide
12.
Li₃PO₄
- Lithium phosphate
13.
TlI₄
- Thallium(I) iodide
14.
Co₃N₂
- Cobalt(III) nitride
15.
Mg₃P₂
- Magnesium phosphide
16.
Ga(NO₃)₃
- Gallium nitrate
17.
Ag₂SO₃
- Silver sulfite
18.
NH₄OH
- Ammonium hydroxide
19.
Al(CN)₃
- Aluminum cyanide
Final Answer:
\[
\boxed{
\begin{array}{ll}
1. & \text{Sodium carbonate} \\
2. & \text{Sodium hydroxide} \\
3. & \text{Magnesium bromide} \\
4. & \text{Potassium chloride} \\
5. & \text{Iron(II) chloride} \\
6. & \text{Iron(III) chloride} \\
7. & \text{Zinc hydroxide} \\
8. & \text{Beryllium sulfate} \\
9. & \text{Chromium(II) fluoride} \\
10. & \text{Aluminum sulfide} \\
11. & \text{Lead(II) oxide} \\
12. & \text{Lithium phosphate} \\
13. & \text{Thallium(I) iodide} \\
14. & \text{Cobalt(III) nitride} \\
15. & \text{Magnesium phosphide} \\
16. & \text{Gallium nitrate} \\
17. & \text{Silver sulfite} \\
18. & \text{Ammonium hydroxide} \\
19. & \text{Aluminum cyanide} \\
\end{array}
