Answer

Answer:

When you place a glass over a candle and the flame goes out, the limiting reactant is oxygen.

Explanation:

Step1: Understand combustion requirements

Combustion needs fuel (wax), oxygen.

Step2: Analyze open - room situation

In open room, oxygen is abundant, wax is limiting.

Step3: Analyze glass - covered situation

When glass covers candle, oxygen inside is quickly used up, becoming limiting reactant as it runs out first and stops combustion.
