Question

A chemical reaction occurs when 2 white solids are stirred together they turn into a slushy white solid and the glass jar feels really cold energy is being ____ by the solids which this means its an ____ reaction
A.) Absorbed, exothermic
B.) Absorbed, endothermic
C.) Released, exothermic
D.) Released, endothermic

Answer 1

Answer:

Absorbed, endothermic

Explanation:

Based on the heat of reaction, chemical reactions may be classified as endothermic or exothermic.

In an endothermic reaction, heat is absorbed from the surrounding. As heat is absorbed from the surrounding, the reaction vessel feels cool when touched.

On the other hand, in an exothermic reaction, heat is given out by the system to the surrounding and the reaction vessel feels hot when touched.

Hence the reaction is endothermic and energy is absorbed during the reaction.
