The correct Answer is:
To solve the question regarding the reactants involved in the general combustion formula for any alkane, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the General Formula of Alkanes**: The general formula for alkanes is given by \( C_nH_{2n+2} \), where \( n \) is the number of carbon atoms. 2. **Write the General Combustion Reaction**: The general combustion reaction for a hydrocarbon can be represented as: \[ C_xH_y + O_2 \rightarrow CO_2 + H_2O \] Here, \( x \) and \( y \) represent the number of carbon and hydrogen atoms, respectively. 3. **Substitute the Alkane Formula**: For alkanes, substitute \( x \) with \( n \) and \( y \) with \( 2n + 2 \): \[ C_nH_{2n+2} + O_2 \rightarrow CO_2 + H_2O \] 4. **Balance the Reaction**: To balance the combustion reaction, we need to determine the amount of \( O_2 \) required: - The number of \( CO_2 \) produced will be equal to the number of carbon atoms, which is \( n \). - The number of \( H_2O \) produced will be half the number of hydrogen atoms, which is \( \frac{2n + 2}{2} = n + 1 \). 5. **Calculate the Oxygen Requirement**: The total oxygen required can be calculated as follows: - Each \( CO_2 \) molecule requires 2 oxygen atoms, contributing \( 2n \) oxygen atoms. - Each \( H_2O \) molecule requires 1 oxygen atom, contributing \( n + 1 \) oxygen atoms. - Therefore, the total oxygen required is: \[ 2n + (n + 1) = 3n + 1 \] Since each \( O_2 \) molecule contains 2 oxygen atoms, the moles of \( O_2 \) required will be: \[ \frac{3n + 1}{2} \] 6. **Final Balanced Equation**: The balanced combustion reaction for any alkane can now be written as: \[ C_nH_{2n+2} + \frac{3n + 1}{2} O_2 \rightarrow n CO_2 + (n + 1) H_2O \] ### Conclusion: The reactants involved in the general combustion formula for any alkane are: \[ C_nH_{2n+2} + \frac{3n + 1}{2} O_2 \]
