exothermic reactions can be shown in hand warmers self heating cans (hot chocolate)
in ENDOTHERMIC reactions heat is taken in
endothermic reaction is shown as a fall in tempreture
endothermic reaction involve sports injury packs like an ice pack
required practical
A) energy released
B) measuring
C) lost to the surroundings
D) neutralisation
energy must always be supplied to break bonds
energy must be supplied to break existing bonds so the bond is an endothermic process
energy is released when new bonds are formed so bonds formation is an exothermic process
in exothermic reactions the energy released by forming bonds greater than the energy used to break them. in endothermic reactions the energy used to break bonds is greater than the energy released by forming them
