Watch the video and fill out the data table.
1. Determine the mass of the zinc that reacted.
5. Determine the ratio: 📷
1. Since you believe that atoms combine in simple whole-number ratios, what do you think is the likely ratio?
2. Based on your findings, what is the empirical formula of zinc chloride?
2. Determine the mass of zinc chloride (guess which one you should use).
3. Determine the mass of chlorine in the zinc chloride.
4. Determine the number of moles of zinc, then the number of moles of chlorine.
3. Suppose that you had not driven off all the water from the zinc chloride. How would this error have affected the ratio in calculation 5?
