$\text{A chemical change..........}$

#### Explanation:

Chemical change is characterized by the formation of new substances and the making and breaking of strong chemical bonds. Usually the best indication that chemical change has occurred is by the observation of colour change, which was observed in this reaction......... So this observed process was likely a.......... ??

Note also that heat was evolved from the process. The process was clearly $\text{exothermic}$.
