or small company chemistry stores might have t o deal with. Through this file it can he determined whether a particular chemical is stocked, how much of any chemical is at present in stock, which items need to be reordered because stocks have fallen below a predetermined limit, etc. The fields used are: 1) Compound Number (allocated by stares for easy reference) 2) Compound Name
3) Phase (gas, liquid or solid at room temperature) 4) Present Stock 5) Minimum Stock (to prompt reordering) 6) Supplier
As part of the interactive exercise, the students attempt to update the stock after a delivery and modify stock records after typical weekly withdrawals as well as finding answers to the questions: Do the stores stock sulfamic acid?
How much acetone is there in stock? Which solids need reordering? What liquids are purchased from the ABC Company? etc. They are also asked to criticize and comment on the use of this particular program as a means of controlling stock records. Physical Constants of Organic Compounds. The data base in the exercise contains information about physical properties of organic compounds. The six fields hold the name, relative molar mass, freezing point, boiling point, density, and refractive index of 100 organic compounds. The questions posed include: Is ethyl nitrite included in the database? What liquids are available with a boiling point between 100 and 120 "C?
Which substances have a refractive index greater than that of tetrachloromethane? What are the boiling points of the C1-C6 alcohols? Whieh liquid has a density >2.00 and a boiling point
