2SO2 + O2 + 2H2O → 2H2SO4 What is the actual yield if the reaction proceeds to 85% completion

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.
