Question

reactions worksheet
when two (ionic) chemicals react, they split into their component ions, and swap partners. the positive ion of one compound binds to the negative ion of the other compound, and vice - versa. in the case of an element reacting with a compound, the ion form of the element binds to its opposite ion of the compound, and the remaining ion binds with itself to form an element.
