Energy is involved in all chemical reactions
When a reaction happen bonds have to be broken and then
remade in different combination

Bond breaking takes in energy

Bond making releases energy

We can calculate the energy release using the following

Where :
C = specific heat capacity ( always 4.2 J / g /
M = mass of whatever is being heated
T = change in temperature ( difference…

Over the whole reaction is less energy is released than
taken in the whole reaction is endothermic
An endothermic reaction is shown by a temperature
An example of endothermic reaction is photosynthesis ­
energy from the sun is taken in
