Thermochemical equations are chemical equations that clearly show the relationship
between mass of products and reactants and enthalpy changes. For example
CH4 (9) + 202 (g) → CO2 (g) + 2H2O (1)
AH = - 890.4 kJ
moles of CH4 = - 890.4 kJ
moles of O2 = - 890.4 kJ
moles of CO2 = - 890.4 kJ
moles of H20 = - 890.4 kJ
- 890.4 kJ
- 890.4 kJ
- 890.4 kJ

Determine the heat produced in the above reaction when 1.6 grams of carbon dioxide is
produced.
Determine the heat produced in the above reaction when 1.6 grams of water is produced.
Does the amount of heat released or absorbed depend on the mass of substance
present? What is your evidence?
