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]
Use the calculator below to balance chemical equations and determine the type of reaction (instructions). Chemical Equation (H2O = H + O) 🛠️
This method separates the reaction into two half-reactions – one for oxidation and one for reduction. Each half-reaction is balanced separately and then combined. Best for: complex redox reactions, especially in acidic or basic solutions.
This experiment involves the synthesis of a metal salt by direct reaction of a metal and a non-metal. Zinc powder is added to a solution of iodine in ethanol. An exothermic redox reaction occurs, forming zinc iodide, which can be obtained by evaporating the solvent. Zn + I 2 → ZnI 2
Enter an equation of an ionic chemical equation and press the Balance button. The balanced equation will be calculated along with the solubility states, complete ionic equation, net ionic equation, spectator ions and precipitates.
Decomposition Reaction: ZnI 2 → Zn + I 2. The compound also interacts with strong bases, such as sodium hydroxide, to form zinc hydroxide and sodium iodide. Reaction with Sodium Hydroxide: ZnI 2 + 2NaOH → Zn (OH) 2 + 2NaI.
17 Οκτ 2014 · Solution. Determine moles I2 by dividing the given mass by its molar mass. I prefer to divide by multiplying by the inverse of the molar mass, mol/g. Calculate moles Zn by multiplying moles I2 by the mole ratio between I2 and Zn in the balanced equation, with Zn in the numerator.
