Chemistry

Synthesis of zinc iodide

How well do your results agree with the law of conservation ofMass ( use percent difference to compare)

% composition of Zn and I:

Convert mass Zn to moles

Convert mass I2 reacted to moles

Using the molar ratios determine the emperical formula for zinciodide

Given:

Mass of empty test tube#1: 22.28g

Mass of test tube #2 + boiling stones: 23.10g

Zn reactant:

Mass of tube #1 + Zn + Iz: 26.33g

Mass of I2: 2.06

Zn

Mass of test tube#1 + remaining Zn: 23.78g

Mass of Zn consumed in the reaction 0.49g

Zinc iodide

Mass of test tube#2+ zinc iodide: 25.64

Mass of Zinc iodide:0.69
