Question

part a. write the chemical formula for each of the following compound.

1. hydrosulfuric acid
2. potassium peroxide
3. ferrous bisulfate
4. ammonium iodate
5. nitric acid

part b. write the chemical name for each of the following compound.

1. $\ce{n_{2}o_{5}}$
2. $\ce{mgcl_{2} \times 6h_{2}o}$
3. $\ce{mn(co_{3})_{2}}$
4. $\ce{h_{3}po_{4}(aq)}$
5. $\ce{co(clo)_{2}}$

Explanation:

Step1: Identify acid components

Hydrosulfuric acid is $H_2S$ (binary acid: $H^+$ + $S^{2-}$).

Step2: Identify peroxide components

Potassium peroxide: $K^+$ + $O_2^{2-}$ → $K_2O_2$.

Step3: Identify bisulfate components

Ferrous bisulfate: $Fe^{2+}$ + $HSO_4^-$ → $Fe(HSO_4)_2$.

Step4: Identify iodate components

Ammonium iodate: $NH_4^+$ + $IO_3^-$ → $NH_4IO_3$.

Step5: Identify nitric acid formula

Nitric acid: $HNO_3$ (oxyacid: $H^+$ + $NO_3^-$).

Step6: Name covalent compound

$N_2O_5$: dinitrogen pentoxide (prefixes for N=2, O=5).

Step7: Name hydrate

$MgCl_2 \cdot 6H_2O$: magnesium chloride hexahydrate (6 = hexa-).

Step8: Name ionic compound

$Mn(CO_3)_2$: manganese(IV) carbonate (Mn charge: +4, $CO_3^{2-}$×2).

Step9: Name aqueous acid

$H_3PO_4(aq)$: phosphoric acid (oxyacid of $PO_4^{3-}$).

Step10: Name hypochlorite compound

$Co(ClO)_2$: cobalt(II) hypochlorite (Co charge: +2, $ClO^-$×2).

Answer:

1. $H_2S$
2. $K_2O_2$
3. $Fe(HSO_4)_2$
4. $NH_4IO_3$
5. $HNO_3$
6. dinitrogen pentoxide
7. magnesium chloride hexahydrate
8. manganese(IV) carbonate
9. phosphoric acid
10. cobalt(II) hypochlorite
