Q55E - Chemistry (OpenStax)

Question

Question: Write the formulas of the following compounds: 

(a) chlorine dioxide 

(b) dinitrogen tetraoxide

(c) potassium phosphide 

(d) silver(I) sulfide 

(e) aluminum nitride 

(f) silicon dioxide

Step-by-Step Solution

Answer

1. ClO₂
2. N₂O₄
3. K₃P
4. Ag₂S
5. AlN
6. SiO₂

Step 1: Writing individual atoms/molecules with their charge

\(C{l^ - }\)\({O^{2 - }}\)\({N^{3 + }}\)\({K^ + }\)\({P^{3 - }}\)\(A{g^ + }\)\({S^{2 - }}\)\(A{l^{3 + }}\)\({N^{3 - }}\)\(S{i^{4 + }}\)

Step 2: Crisscrossing charges with elements present in the compound

After crisscrossing, we get

1. ClO₂

2. N₂O₄

3. K₃P

4. Ag₂S

5. AlN

6. SiO₂
