Question

Choose the nonmetallic oxides from the following:

• A. $\text{FeO}$
  
• B. ${\text{Al}}_2{\text{O}}_3$
  
• C. ${\text{Fe}}_2{\text{O}}_3$
  
• D. ${\text{CO}}_2$
  

Answer 1

The correct option is D ${\text{CO}}_2$


The nonmetallic oxide is ${\text{CO}}_2$. The other three options $\text{FeO},{\text{Al}}_2{\text{O}}_3$ and ${\text{Fe}}_2{\text{O}}_3$ have the metals iron (Fe) and aluminium (Al).
