It's probably not worth going into, but the equation is very wrong. There is no elemental calcium present at the beginning, coke does not contain any significant amount of phosphoric acid (instead, a collection of phosphates), and the reaction certainly doesn't produce hydrogen gas (boom!) I'll give it five points out of a hundred for being balanced.
