The first synthesis reaction used solid zinc and solid iodine to yield solid zinc iodide as shown in the chemical equation below

The first synthesis reaction used solid zinc and solid iodine to yield solid zinc iodide as shown in the chemical equation below. The chemical reaction was carried out four additional times as shown by the data table below. Predict both the final temperature and the temperature change of the surroundings for trial 3. Explain your reasoning for your prediction by defining the relationship between the masses of the reactants (solid zinc and solid iodine) and the temperature change of the surroundings as either direct, inverse, or having no relationship.
