Valery Baldwin · Answer 1

C. 45 degrees Celsius

Explanation:

Exothermic reactions are when the temperature goes up in a chemical reaction.

Draven Edwards · Answer 2

The correct option is C. 45 degrees Celsius.

Explanation:

The energy is the ability to do a job or to produce heat. And chemical reactions involve a rearrangement of atoms between substances with breakage or formation of chemical bonds. In general, this formation or breakdown of chemical bonds is accompanied by changes in the energy of the system.

An exothermic reaction is one where energy is released from the system into the environment in the form of heat.

This happens because the energy that the reagent molecules contain is greater than the energy that the product molecules contain. Then part of this chemical energy is released. This increases the temperature around the system where the reaction occurs. Taking this into account, it is possible to say that the correct option is: C. 45 degrees Celsius.
