Final answer:
The combustion of 16 g of methane generates 55.5 kJ of heat.
Step-by-step explanation:
The combustion of methane is an exothermic reaction that releases heat. The thermochemical equation for the reaction is:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(ℓ) + 890.4 kJ
From this equation, we can see that 1 mole of methane produces 890.4 kJ of heat energy. To calculate the heat generated when 16 g of methane undergoes complete combustion, we can use dimensional analysis:
16 g CH₄ × (1 mol CH₄ / 16.04 g CH₄) × (890.4 kJ / 1 mol CH₄) = 55.5 kJ
Therefore, when 16 g of methane undergoes complete combustion, 55.5 kJ of heat is generated.
