Let's analyze the given chemical equation and balance it correctly.
The given chemical equation is:
[tex]\[ 2 C_4H_{10} + 10 O_2 \longrightarrow \square + 10 H_2O \][/tex]
We need to identify the incorrect coefficient in this equation.
### Step-by-Step Analysis:
1. Identify the reactants and products:
- Reactants: Butane ([tex]\(C_4H_{10}\)[/tex]) and Oxygen ([tex]\(O_2\)[/tex])
- Products: Carbon Dioxide ([tex]\(CO_2\)[/tex]) and Water ([tex]\(H_2O\)[/tex])
2. Write the correct and balanced chemical equation:
The molecular formula of butane ([tex]\(C_4H_{10}\)[/tex]) suggests that one molecule of butane will produce four molecules of carbon dioxide ([tex]\(CO_2\)[/tex]) when it combusts completely.
The generally balanced equation for the complete combustion of butane is:
[tex]\[ 2 C_4H_{10} + 13 O_2 \longrightarrow 8 CO_2 + 10 H_2O \][/tex]
3. Compare given coefficients with the correct balanced equation:
- Given for [tex]\(O_2\)[/tex]: 10
- Correct for [tex]\(O_2\)[/tex]: 13
### Conclusion:
The coefficient for [tex]\(O_2\)[/tex] in the chemical equation is incorrect. The given chemical equation provides a coefficient of [tex]\(10\)[/tex] for [tex]\(O_2\)[/tex], whereas the correct coefficient should be [tex]\(13\)[/tex].
Thus, the part of the chemical equation that is incorrect is the coefficient for [tex]\(O_2\)[/tex]. The incorrect value is [tex]\(10\)[/tex], and the correct value should be [tex]\(13\)[/tex].
