Question

A non-metal X is an important constituent of our food. It forms two oxides Y and Z. Y is toxic and causes suffocation and even death while Z is responsible for global warming. Identify X, Y and Z.

• A. $X=C,Y=CO,Z=C{O}_2$
• B. $X=S,Y=S{O}_2,Z=S{O}_3$
• C. $X=P,Y=P_2{O}_3,Z=P_2{O}_5$
• D. $X=O,Y=O_2,Z=O_3$

Answer 1

The correct option is A $X=C,Y=CO,Z=C{O}_2$

The non-metal $X$ is carbon which is an important constituent of our food. Carbon forms two oxides $Y\left(CO\right)$ and $Z\left(C{)}_2\right)$. $CO$ is toxic and causes suffocation and even death while $C{O}_2$ is responsible for global warming.
