Exothermic And Endothermic Reactions Flashcards
Many Reactions Transfer Energy from the ______________ Chemicals to their Surroundings. These are Called ______________ Reactions.
Reacting…Exothermic…
The Energy _______________ From the Reacting Chemicals Often Heats Up the Surroundings.
Transferred.
Other Reactions Transfer Energy From the Surroundings to the Reacting Chemicals. These are Called ______________ Reactions. As they Take in Energy From Their Surroundings, these Reactions Cause a Fall in ________________ as they Happen.
Endothermic…Temperature…
Burning of Fuels is an Example of _______________ Reactions. When Methane Burns, it gets _______________ and Releases Energy to its Surroundings.
Exothermic…Oxidised…
________________ Reactions Between Acids and Alkalis are Also Exothermic. You can Easily Measure the _______ in Temperature use Simple Apparatus.
Neutralisation…Rise…
Products of Exothermic Reactions have a Lower Energy Content than the ____________. The Actual Differences in Energy are Usually Expressed in ____________ Per Mole (kJ/Mol).
Reactants…Kilojoules…
Endothermic Reactions are Much Less ___________ than Exothermic Ones.
Common.
Thermal ________________ Reactions are Also Endothermic.
Decomposition.
In Endothermic Reactions the Products have a _________ Energy Content than the Reactants, so Energy is ______________ From the Surroundings.
Higher…Transformed…
