Question: 1 / 605

Which chemical is highly reactive and a potential fire hazard under certain conditions?

Hydrogen peroxide

Hydrogen peroxide is known for its high reactivity, particularly due to the presence of its unstable oxygen-oxygen bond. Under certain conditions, such as in concentrated forms or when it comes into contact with organic materials or certain catalysts, it can decompose violently, releasing oxygen gas and heat. This decomposition can create a fire hazard because the released oxygen can enhance the combustion of flammable materials.

While carbon monoxide is toxic and can pose risks in terms of suffocation and health hazards, it is not classified as highly reactive in the same way hydrogen peroxide is. Carbon dioxide is a non-flammable gas that is actually used to extinguish fires, and nitrogen is inert under most conditions, making it generally safe and not reactive. Therefore, hydrogen peroxide stands out as the chemical that poses a risk of fire under specific reactive conditions.
