Question

science
what two common substances create a toxic
chlorine gas when combined?
alcohol and baking soda
water and creatine
bleach and vinegar
natron and lemon juice

Explanation:

Bleach (sodium hypochlorite, \( \text{NaClO} \)) reacts with vinegar (acetic acid, \( \text{CH}_3\text{COOH} \)). The reaction produces chlorine gas (\( \text{Cl}_2 \)), which is toxic. The chemical reaction is \( \text{NaClO}+2\text{CH}_3\text{COOH}
ightarrow \text{Cl}_2\uparrow+\text{NaCl}+2\text{CH}_3\text{COONa}+\text{H}_2\text{O} \). Alcohol and baking soda, water and creatine, natron and lemon juice do not produce chlorine gas.

Answer:

Bleach and vinegar
