Question

chemical reaction in which an element or compound reacts with oxygen, often producing energy in the form of heat and light
○ combination (synthesis)
○ decomposition reaction
○ combustible
○ combustion reaction

Explanation:

To solve this, we analyze each option:

• Combination (synthesis) reaction: A reaction where two or more substances combine to form a single product, not specifically with oxygen producing heat/light.
• Decomposition reaction: A reaction where a compound breaks down into simpler substances, not involving reaction with oxygen to produce heat/light.
• Combustible: A substance that can catch fire and burn, not a reaction.
• Combustion reaction: A chemical reaction where an element or compound reacts with oxygen, often producing heat and light (like burning of fuels).

Answer:

D. combustion reaction
