Final answer:
To find the heat released by the combustion of 4 moles of C₄H₁₀, we need the specific enthalpy of combustion for butane. Typically, the heat released in exothermic reactions like combustion is reported as a negative value and is the product of the molar enthalpy and the number of moles.
Step-by-step explanation:
To calculate heat released when 4 moles of C₄H₁₀ is combusted, we need the balanced chemical equation for the combustion of butane (C₄H₁₀) and its enthalpy of combustion. Unfortunately, the provided references do not include the specific enthalpy of combustion for butane. However, for example, the combustion of 1 mole of methane (CH₄) releases 890.4 kJ of heat. If we had the enthalpy value for butane, we would multiply the molar enthalpy by the number of moles being combusted. Since the reaction is exothermic, the heat of the reaction would typically be expressed as a negative value.
