![**Combustion of Octane Problem**
**Problem Statement**:
Using the following equation for the combustion of octane, calculate the heat associated with the formation of 100.0 g of carbon dioxide. The molar mass of octane is 114.23 g/mol. The molar mass of carbon dioxide is 44.0095 g/mol.
**Chemical Equation**:
\[2 \text{C}_8\text{H}_{18} + 25 \text{O}_2 \rightarrow 16 \text{CO}_2 + 18 \text{H}_2\text{O}\]
\[\Delta H_{rxn} = -11018 \text{ kJ}\]
**Options**:
A) -11018 kJ
B) -12520 kJ
C) -1001 kJ
D) -1565 kJ
E) -1391 kJ
**Explanation**:
This problem involves calculating the enthalpy change associated with the production of a specified amount of carbon dioxide from the combustion of octane. Use stoichiometry and the given molar masses to find the correct answer choice.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fda3527a5-574a-4c7c-8d19-c2922dfd16bf%2F9f3bfb14-d04f-4796-965a-83c71c8b48ec%2Flxpib1_processed.jpeg&w=3840&q=75)
