Chapter , Problem 1PE

(choose chapter or problem)

Write the balanced equation for the reaction that occurs when ethylene glycol, \(\mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{OH})_{2}\), burns in air.

(a) \(\mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{OH})_{2}(l)+5 / 2\ \mathrm{O}_{2}(g) \longrightarrow 2\ \mathrm{CO}_{2}(g)+3\ \mathrm{H}_{2} \mathrm{O}(g)\)

(b) \(2\ \mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{OH})_{2}(l)+5\ \mathrm{O}_{2}(g) \longrightarrow 4\ \mathrm{CO}_{2}(g)+6\ \mathrm{H}_{2} \mathrm{O}(g)\)

(c) \(\mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{OH})_{2}(l)+3\ \mathrm{O}_{2}(g) \longrightarrow 2\ \mathrm{CO}_{2}(g)+3\ \mathrm{H}_{2} \mathrm{O}(g)\)

(d) \(\mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{OH})_{2}(l)+5\ \mathrm{O}(g) \longrightarrow 2\ \mathrm{CO}_{2}(g)+3\ \mathrm{H}_{2} \mathrm{O}(g)\)

(e) \(4\ \mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{OH})_{2}(l)+10\ \mathrm{O}_{2}(g) \longrightarrow 8\ \mathrm{CO}_{2}(g)+12\ \mathrm{H}_{2} \mathrm{O}(g)\)
