Chemicals that ignite when combined create what type of reaction?

Chemicals that ignite when combined create what type of reaction?

• A. a hyperbolic
• B. an exothermic
• C. a congenial
• D. a cryogenic

Answer: (B)

In chemistry, a reaction that releases energy as heat to the surroundings is exothermic. When two reactive chemicals ignite upon mixing, a rapid release of energy occurs, often producing heat and light. That energy release is the defining feature of an exothermic reaction, which is why this option fits best. The other terms don’t apply: hyperbolic is a math/curve term, congenial means friendly, and cryogenic refers to very low temperatures—neither describes a reaction that releases energy.
