Consider the problem below:

Equation 1: 
\[ 4 \text{CO}_{(g)} + 4 \text{H}_2\text{O}_{(l)} \rightarrow \text{C}_4\text{H}_8\text{(l)} + 4 \text{O}_2\text{(g)} \] 
\(\Delta H = 890.6 \, \text{kJ/mol}\)

Equation 2: 
\[ \text{CO}_2\text{(g)} \rightarrow \text{CO}_{(g)} + \frac{1}{2} \text{O}_2\text{(g)} \] 
\(\Delta H = 90.6 \, \text{kJ/mol}\)

Equation 3: 
\[ \text{C}_4\text{H}_8\text{(l)} + 6 \text{O}_2\text{(g)} \rightarrow 4 \text{CO}_2\text{(g)} + 4 \text{H}_2\text{O}_{(l)} \] 
\(\Delta H = ???????\)

To find \(\Delta H\) for equation 3 you must:

- Multiply equation 1 only
- Multiply equation 2 only
- Multiply equation 1 and equation 2
- Multiply neither equation 1 nor equation 2
