When a nonmetal oxide reacts with water, it forms an oxoacid with the same nonmetal oxidation state. Give the name and formula of the oxide used to prepare each of these oxoacids: (a) hypochlorous acid; (b) chlorous acid; (c) chloric acid; (d) perchloric acid; (e) sulfuric acid; (f) sulfurous acid; (g) nitric acid; (h) nitrous acid; (i) carbonic acid; (j) phosphoric acid.

1) dichlorine monoxide (Cl2O

2) dichlorine trioxide (Cl2O3)

3) dichlorine pentoxide (Cl2O5)

4) dichlorine heptoxide (Cl2O7)

5) sulfur trioxide (SO3)

6) sulfur dioxide (SO2)

7) dinitrogen pentoxide (N2O5)

8) dinitrogen trioxide (N2O3)

9) carbon dioxide (CO2)

10) phosphorous trioxde (PO3)

Explanation:

Step 1: Data given

a) hypochlorous acid = HOCl

HClO is formed when dichlorine monoxide (Cl2O) is dissolved in water.

Cl2O (g) + H2O (l) → 2 HClO (aq)

(b) chlorous acid = HClO2

HClO2 is formed when dichlorine trioxide (Cl2O3) is dissolved in water.

Cl2O3 (g) + H2O (l) → 2HClO2 (aq)

(c) chloric acid = HClO3

HClO3 is formed when dichlorine pentoxide (Cl2O5) is dissolved in water

Cl2O5 (g) + H2O (l) → 2HClO3 (aq)

d) perchloric acid = HClO4

HClO4 is formed when dichlorine heptoxide (Cl2O7) is dissolved in water

Cl2O7 (g) + H2O (l) → 2HClO4 (aq)

(e) sulfuric acid = H2SO4

H2SO4 is formed when sulfur trioxide (SO3) is dissolved in water

SO3 (aq) + H2O (l) → H2SO4 (aq)

(f) sulfurous acid = H2SO3

H2SO3 is formed when sulfur dioxide (SO2) is dissolved in water

SO2 (aq) + H2O (l) → H2SO3 (aq)

(g) nitric acid = HNO3

HNO3 is formed when dinitrogen pentoxide (N2O5) is dissolved in water

N2O5 (aq) + H2O (l) → 2HNO3 (aq)

(h) nitrous acid = HNO2

HNO2 is formed when dinitrogen trioxide (N2O3) is dissolved in water

N2O3 (aq) + H2O (l) → 2HNO2 (aq)

(i) carbonic acid = H2CO3

H2CO3 is formed when carbon dioxide (CO2) is dissolved in water

CO2 (g) + H2O (l) → H2CO3 (aq)

(j) phosphoric acid = H3PO4

H3PO4 is formed when phosphorous trioxde (PO3) is dissolved in water

PO3 + 2H2O → H3PO4 + OH
