Class practical. Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph.Lesson organisation. This is intended as a class practical.lass practical.

Special Measures of Incidence. Morbidity rate is the incidence of non-fatal cases of a disease in a population during a specified time period. For example, during 1982 there were 25,520 non-fatal cases of TB in the US population. The mid-year population was estimated at 231,534,000.
