Question

this passage describes a chemical reaction. read the passage. then, follow the instructions below.
did you know that glow sticks give off light because of a chemical reaction? a glow stick contains two compounds: hydrogen peroxide (h₂o₂) and diphenyl oxalate (c₁₄h₁₀o₄), which are separated by a barrier inside the glow stick. when you bend a glow stick, the barrier breaks and the substances mix, forming phenol (c₆h₆o) and carbon dioxide (co₂). the energy released by this reaction makes the glow stick give off colored light.
complete the table to classify the substances in this chemical reaction.

Explanation:

Reactants are the substances that start a chemical reaction, and products are the substances formed as a result of the reaction. The passage states that hydrogen peroxide ($H_2O_2$) and diphenyl oxalate ($C_{14}H_{10}O_4$) react (they are separated by a barrier initially, and when the barrier breaks, they mix to react). The products formed are phenol ($C_6H_6O$) and carbon dioxide ($CO_2$).

Answer:

• Carbon dioxide ($CO_2$): Product
• Diphenyl oxalate ($C_{14}H_{10}O_4$): Reactant
• Hydrogen peroxide ($H_2O_2$): Reactant
• Phenol ($C_6H_6O$): Product
