What laboratory apparatus used to support the set up for distillation?
A ring stand with a ring attached will be helpful.
Why is it necessary for us to know the names and functions of laboratory apparatus?
Simply because each piece of apparatus has set functions ! For example - it's no good trying to separate chemicals with different boiling points in an ordinary flask. You need the addition of the fractional distillation tube, so that the one with the lower boiling point will condense back into the flask. You would need to know what a fractional distillation tube was - and what it looked lke in order to select the correct piece of equipment !
Why is the test tube with distilled water included in the laboratory activity?
the purpose of distilled water is so that chemicals in the water do not interfere with the experiment :)

Why is it necessary to ensure work efficiency and safety in the lab area?
Before beginning any work in a laboratory, you need to be familiar with that particular lab's rules for safety. This includes the location of all safety related equipment and a working knowledge of their operation. As far as efficiency, if you will be setting up an experiment you need to know the lab procedure ahead of time, if possible. Also, it helps to know in your head how you will set up the experiment in advance to save time getting started. Finally, use care when conducting an experiment so you don't have to repeat anything.So there will be no accidents.
