Example:
Decomposition of mercuric oxide HgO to mercury Hg and oxygen O2 gas, requires
87.1kJ of heat,
HgO(s) Hg(l) + O2(g) ΔH = + 87.1kJ (needs to absorb energy)
1. Combustion of hexane, C6H12 to carbon dioxide gas and water, releases 3923.9kJ
of heat.
2. Reaction between solid phosphorous, P4 and oxygen gas, produces P3O6 and
1640.1kJ of heat.
3. One mole ammonium nitrate (NH4NO3) dissolves in water to produce aqueous
ammonium ions and nitrate ions accompanied by the absorption of 28.1 kJ of heat.
4. Formation of carbon dioxide gas from carbon (graphite) and oxygen yields 393.5
kJ of heat.
