It is important because the people are expressing what they feel, by telling you to try and help them do something that helps them, it also is important because they are able to have a voice.
Answer:
The reaction is exothermic.
Explanation:
Enthalpy of Formation (ΔHrxn):
It is regarded as the variation in enthalpy when a mole of substance is produced at standard temperature and pressure through its pure elements under same conditions.
1) ΔHrxn = negative
When the energy is produced in the course of production of compound in a chemical reaction. It is known as Exothermic reaction.
2) ΔHrxn = posituve
When the energy taken in in the course of the production of compound in a chemical reaction. It is known as Endothermic reaction
The of production of carbon dioxide is negative. It implies that the ΔHrxn is an exothermic reaction.
