Question

when food is exposed to air, it can lose electrons. this loss of electrons creates reactive molecules that work to destroy the chemical bonds in the food, causing it to spoil. what are these reactive molecules called?
a. free radicals
b. spoiling molecules
c. oxygen molecules
d. hydrogen molecules

Explanation:

Free radicals are unstable molecules that have unpaired electrons. When food loses electrons upon exposure to air, the resulting reactive molecules are free - radicals which can break chemical bonds in food and cause spoilage.

Answer:

A. Free radicals
