Balancing Equations Worksheet NAME ___ ________ Directions Please read over your textbook for background information! There are 30 reactions presented below. Although each reaction is verbally stated, all formulas have already been correctly written and the reactions are presented as unbalanced skeleton reactions. Reading over the verbal reactions should help with practicing your nomenclature and formula writing. [You may also notice that the classifications of the reactions may or may not match the 4 types we are using in our course.] To complete this experiment, simply balance each of the reactions. (Remember – sometimes the balanced mole ration for the substances in an equation can all be 1!) A. Combination Reactions 1. Diphosphorus trioxide is formed by direct combination of its elements.
