1)
Introduction…
· define synthesis
· explain goal of lab… what we hope to learn… how the experiment was set up (variable and control)
1)
Discuss the procedure
a bit…
· spontaneous reaction, what gas was produced (how
you know), why the test tubes were left overnight, what was done on second day
(and why)
· are there any char. property differences you noted
between the original zinc and the compound zinc chloride?
1)
SIGNIFICANCE OF CLASS
RESULTS
· is there a fixed ratio of zinc reacted compared to the mass of zinc chloride that forms? (How do you know?)
· were any values thrown out? What might have happened in their lab?
· what is the class average for the ratio, and how
does it compare to the “actual value”?
