Answer
A. Exothermic
Explanation
## Step 1This problem is about thermochemistry, a branch of chemistry that involves the study of the relationship between the heat and chemical reactions. The two key terms in this context are:### **Exothermic**: Reactions that release heat.### **Endothermic**: Reactions that absorb heat.## Step 2The change in temperature is a key indicator of the nature of the reaction taking place. If the temperature increases, it means that heat has been released into the surroundings. This is a characteristic of exothermic reactions.## Step 3In the given problem, the temperature increased from 15.0 degrees Celsius to 27.5 degrees Celsius. This increase in temperature indicates that heat was released into the surroundings, which is a characteristic of exothermic reactions.## Step 4It's important to disregard any unrelated data such as "Emely" and "Aguirre" to come across the right conclusion.
