29. Separation Lab  You must not loose any material (Law of Conservation of Mass).  Measure out sand, salt and ammonium chloride as directed. Divide and conquer Divide and conquer No fire alarms!!! No fire alarms!!!  Quantitative Lab Measure, measure, measure – Be sure it’s cold though! Measure, measure, measure – Be sure it’s cold though!
