Question

A compound containing silicon and oxygen is:

• A. Common salt
• B. Sand
• C. Sodium carbonate
• D. Sugar

Answer 1

The correct option is B

Sand

Explanations of correct option:

Option B: Sand$\left({\mathrm{SiO}}_2\right)$:

• In chemistry, sand is known as silica which is the chemical compound composed of silicon (Si) and oxygen (O) with the chemical formula $\left({\mathrm{SiO}}_2\right)$, or silicon dioxide.
• It is a compound containing silicon and oxygen

Explanations of incorrect options:

Option A: Common salt$\left(NaCl\right)$

• Common salt is a compound of Sodium (Na) and Chlorine (Cl)
• It is not a compound containing silicon and oxygen

Option C: Sodium carbonate$\left(N{a}_{2}C{O}_3\right)$

• Sodium carbonate is a compound of Sodium (Na), carbon (C), and oxygen (O).
• It is not a compound containing silicon and oxygen

Option D: Sugar$\left(C_{12}{H}_{22}{O}_{11}\right)$

• Sugar is a compound of carbon (C), hydrogen (H), and oxygen (O).
• It is not a compound containing silicon and oxygen

Thus, option (B) i.e., Sand is correct.
