Question

1.) A student performs a reaction and determines the enthalpy change (H) to be 31.4 kJ. Will the temperature of the surrounding solution increase or decrease as a result of this chemical process? 2.) If you hold 3 grams of ice in your hand at room temperature, your hand will become cold. a.) Is the reaction H2O (s) ----> H2O (l) endothermic or exothermic? b.) In which direction does heat flow?

Step 1

) If the enthalpy change (H) is positive, it means the reaction is endothermic, meaning it absorbs heat from the surroundings. If it's negative, the reaction is exothermic, meaning it releases heat to the surroundings. In this case, the enthalpy change is positive Show more…
