4. Did the temperature go up or down? How much?
5. Is this an exothermic or endothermic reaction?
Temperature change, °C (AT)
6. Think of some other chemical reactions. List them and the type of reaction: exothermic
or endothermic.
Example: Burning coal - exothermic

4) The temperature went up by 3 degrees

5) The reaction is exothermic

6) The burning of hydrocarbons is an exothermic reaction

What is enthalpy?

One of the characteristics of a chemical change is that there could be a change in the temperature of the system. The temperature of the system could be found to have been increased or decreased as the case may be.

In any case, the change in the temperature of the system is what is going to tell is whether the reaction was exothermic or endothermic. If the reaction is endothermic, there is going to be a drop in temperature but if the reaction is exothermic, there is going to be an increase in temperature.

Now we can see from the table that the temperature is increasing by a factor of about three degrees so we can say that the reaction is exothermic.
