First, we set all coefficients to 1: 1 Zn + 1 I 2 = 1 ZnI 2. For each element, we check if the number of atoms is balanced on both sides of the equation. Zn is balanced: 1 atom in reagents and 1 atom in products. I is balanced: 2 atoms in reagents and 2 atoms in products.
Word Equation. Zinc + Iodine = Zinc Iodide. Zn + I = ZnI2 is a Synthesis reaction where one mole of Zinc [Zn] and two moles of Iodine [I] combine to form one mole of Zinc Iodide [ZnI 2]

Balancing a Chemical Equation. Because the identities of the reactants and products are fixed, the equation cannot be balanced by changing the subscripts of the reactants or the products. To do so would change the chemical identity of the species being described, as illustrated in Figure 7.4.1 7.4. 1.
Preparation. It can be prepared by the direct reaction of zinc and iodine in water [1] or in refluxing ether. [2] or by treating zinc with iodine in aqueous solution: [3] Zn + I 2 → ZnI 2. Structure as solid, gas, and in solution. The structure of solid ZnI 2 is unusual relative to the dichloride.
