Question

What does pentane plus (`C_5H_12`) oxygen yield?

Answer 1

Well, complete combustion yields carbon dioxide, and water, and energy..........

Explanation:

`C_5H_12(l) + 8O_2(g) rarr 5CO_2(g) + 6H_2O+Delta`

Is this balanced? How do you represent the combustion of heptane, `C_7H_16`?

Also try to represent the combustion of hexanes, `C_6H_14`; in this instance (an even-numbered alkane), you have to use fractional coefficients, or double the equation.
