Answer
Brief Explanations:
Exothermic reactions release energy and can occur spontaneously. Endothermic reactions absorb energy and may not occur spontaneously. Melting of ice requires heat (absorbs energy), so it's endothermic. A reaction that releases energy and doesn't need initial energy to occur is exothermic, and a reaction that absorbs energy and requires energy to occur is endothermic.
