Answer:

Cβ‚ˆHβ‚β‚ˆ(l) + Oβ‚‚(g) β‡’ COβ‚‚(g) + Hβ‚‚O(l)

Explanation:

Let's consider the unbalanced equation for the combustion reaction of octane.

Cβ‚ˆHβ‚β‚ˆ(l) + Oβ‚‚(g) β‡’ COβ‚‚(g) + Hβ‚‚O(l)

We can begin balancing H atoms by multiplying Hβ‚‚O by 9, and C atoms by multiplying COβ‚‚ by 8.

Cβ‚ˆHβ‚β‚ˆ(l) + Oβ‚‚(g) β‡’ 8 COβ‚‚(g) + 9 Hβ‚‚O(l)

Finally, we get the balanced equation by multiplying Oβ‚‚ by 12.5.

Cβ‚ˆHβ‚β‚ˆ(l) + 12.5 Oβ‚‚(g) β‡’ 8 COβ‚‚(g) + 9 Hβ‚‚O(l)
