Two examples of conversion of other forms of energy into chemical energy are given in terms of chemical equations


2H2O = (energized) 2h2 + O2
2nacl (melt) = (electrify) 2Na + Cl2



Does chemical reaction have energy change? Is there an example of wood without energy change?


No, any chemical reaction has to absorb or release energy
