Indicate if the statements below best describe an ENDOthermic or EXOthermic process. Enter either endo or exo in each blank
A reaction has a negative enthalpy change
Energy is added in order to break a chemical bond
A reaction takes place in water where the water increases in temperature
Upon reaction, the energy of the products is lower than the energy of the reactants
When holding ice in your hand, the ice melts and your hand becomes cold
During reaction, the energy of the system increases
A reaction has a negative enthalpy change
that means energy is released
EXOthermic
Energy is added in order to break a chemical bond
ENDOthermic
A reaction takes place in water where the water
increases in temperature
temperature of water increases that means energy is released from
the reaction
EXOthermic
Upon reaction, the energy of the products is lower than
the energy of the reactants
product has lesser energy that means energy is released
EXOthermic
When holding ice in your hand, the ice melts and your
hand becomes cold
since ice melts it absorbs heat
ENDOthermic
During reaction, the energy of the system
increases
product has more energy that means energy is added
ENDOthermic
