Exothermic And Endothermic Reactions Flashcards
Where is energy in chemical reactions
Energy is conserved
What is the law of conservation?
The law of conservation states that energy can’t be created nor destroyed only transferred into different states
What is the definition of exothermic
When In a chemical reaction energy is realised into the surroundings
What’s is the definition of endothermic
When In a chemical reaction energy is taken in from the surrounding
What are examples of exothermic reactions
Combustion, neutralisation
Oxidation
What are examples of endothermic reactions
Ice packs ,
Thermal decomposition
What is a calorimeter
an apparatus for measuring the amount of heat involved in a chemical reaction or other process.
What’s is the definition for oxidation
A reaction in which Oxygen is added or electrons are lost
What’s is the process called when a reaction in which a compound is broken down by heat
Thermal decomposition
What is the definition for neutralisation
A reaction between an acid and alkali
