Carbon disulfide burns in oxygen to yield carbon dioxide and sulfur dioxide according to the chemical equation CS2(ℓ) + 3 O2(g) −→ CO2(g) + 2 SO2(g). If 1.33 mol of CS2 is combined with 1.83 mol of O2, identify the limiting reactant. 1. CO2 2. O2 3. CS2 4. SO2.How much excess reactant remains? Answer in units of mol. How much CO2 is formed? Answer in units of mol. How much SO2 is formed?Answer in units of mol

option c: 1605.1 kj

the balanced chemical reaction for combustion of methane is as follows:

here, enthalpy formation of is -74.7 kj/mol, 0 kj/mol, -393.5 kj/mol and -241.82 kj/mol respectively.

the heat released or can be calculated as follow:

putting the values,

thus, heat released by combustion of 1 mol of methane is 802.54 kj/mol. thus, for 2 mol, heat released will be:

therefore, heat released by the combustion of 2 mol of methane is 1605.1 kj.
