Answer:
The temperature of the reaction mixture increases.
Explanation:
One very good indicator that a chemical reaction has taken place is that there is a temperature change about the reaction.
Either an emission of heat involving the reaction milieu becoming hotter or an absorption of heat making the environment colder.
- Enthalpy changes of reactions are good parameters to measure whether or not a reaction has taken place.
- There is no color change, and mass is always conserved for most reaction, so we cannot use these tools for assessing whether a reaction has occurred or not.
Ca= Calcium, and (CO3) = Chloride. Ca(CO3) is Calcium Chloride!
