A
exothermic
2
Q

A
exothermic
3
Q
melting ice
A
endothermic
4
Q
decompositition of calcium carbonate
A
endothermic
5
Q
what is exothermic
A
it releases energy to the surroundings
6
Q
what is endothermic
A
reactants take in energy from their surroundings
7
Q
if the temperature goes up in an experiment which is it
A
exothermic because it’s released thermal energy to the surroundings
8
Q
if the temperature stays the same in an experiment which is it
A
exothermic because it’s neutralisation which releases energy to its surroundings and just needs longer
9
Q
if the temperature goes down in an experiment which is it
A
endothermic because it took energy from the surroundings
10
Q
which is bond breaking
A
endothermic (energy in)
11
Q
which is bond making
A
exothermic (energy out)
