Question

Propane, `C_3H_8`, is frequently used in camping stoves. When propane undergoes combustion, what are the products formed?

Answer 1

Upon complete combustion, propane gives carbon dioxide and water, as do all the hydrocarbons.

Explanation:

Because of the short carbon chain, and its volatility, propane is fairly clean burning:

`C_3H_8(g) + 5O_2(g) rarr 3CO_2(g) +4H_2O(g)+Delta`

What does the `Delta` symbol represent in the given reaction? It too may be quantitatively measured and predicted.
