Question

1. choose the best answer using the table.

chemical compounds
compound | chemical formula | elements
sand | sio₂ | silicon and oxygen
sugar | c₁₂h₂₂o₁₁ | carbon, hydrogen, and oxygen
lime | cao | calcium and oxygen
salt | nacl | sodium and chlorine
hydrogen peroxide | h₂o₂ | hydrogen and oxygen
carbon dioxide | co₂ | carbon and oxygen

which compound has the chemical formula c₁₂h₂₂o₁₁?
∘ carbon dioxide
∘ sugar
∘ hydrogen peroxide
∘ salt

Explanation:

Step1: Check each compound's formula

• Carbon dioxide: Formula is \( CO_2 \), not \( C_{12}H_{22}O_{11} \).
• Sugar: Formula is \( C_{12}H_{22}O_{11} \) (matches the given formula).
• Hydrogen peroxide: Formula is \( H_2O_2 \), not \( C_{12}H_{22}O_{11} \).
• Salt: Formula is \( NaCl \), not \( C_{12}H_{22}O_{11} \).

Answer:

sugar
