Final answer:
Calculating the enthalpy of combustion for carbon disulfide would require the enthalpy change value per mole, which must be multiplied by the number of moles being burned. The example of methane illustrates this process, where the enthalpy change is simply the known enthalpy per mole times the amount of moles combusted.
Step-by-step explanation:
To calculate the enthalpy of combustion of carbon disulfide (CS2), we would need the balanced chemical equation for the combustion of CS2 and the enthalpy changes for the products and reactants. Unfortunately, the provided information does not contain the relevant data for carbon disulfide specifically.
However, I can explain the process using the example of methane (CH4) since the principle is the same. The calculation involves determining the amount of heat released when a certain number of moles of the substance burns completely. As per the given details, the combustion of 1 mole of methane releases 890.4 kJ. Knowing this, the enthalpy change for the combustion of any amount of methane can be found by multiplying the amount in moles by 890.4 kJ/mol.
For carbon disulfide, if we had its enthalpy change for combustion per mole, we would do a similar multiplication. To get a more accurate answer, you should refer to a data table listing the enthalpies of combustion for various substances, find the value for carbon disulfide, and apply the same principle as demonstrated with methane.
