A beehive shelf is a piece of laboratory equipment, usually of pottery, used to support a receiving jar or tube while a gas is being collected over water with a pneumatic trough.
Glass rods are used in labs for stirring because they are inert and do not react with the chemicals being mixed. They are also transparent, allowing for easy observation of the mixing process. Additionally, glass rods are easy to clean and sterilize, making them reusable.

Ammonia is called Ammonia only in chemistry. While writing reactions, we use its symbol NH(3).
Demineralised water does not have an expiration date or shelf life as long as it is stored properly in a clean and sealed container. However, it is recommended to use it within a reasonable timeframe to prevent any contamination.
"Ate" is used in chemistry to indicate a negatively charged ion or compound, typically formed by the combination of a metal and oxygen.
No. The term "distilled" is an adjective used to refer to a substance that has been purified by boiling it to separate it from less volatile impurities. For example chemistry labs often use distilled water.
Beakers are commonly found in chemistry labs. They are made of glass and have measurements along the sides. To use a beaker, pour in the wanted amount of liquid to the measurements you want. Beakers are mainly used to see chemical reactions.

You blow it to smithereens or you simply use bee killer.
In pool maintenance we use a bottle labeled R-004 to test the ph. In chemistry labs, you might use phenolphthalein solution, litmus paper, or other pH test paper, depending on the situation.
This sounds like a question proposed by a chemistry education professor. I'm a high school chemistry teacher (16 years) and unsure why we push constructivism in chemistry labs. It seems unsafe to have kids design labs. Liability is much greater for the school. Well written labs will develop the skills students need to construct knowlege and attain understanding. Class discussion and post-lab analysis are wonderful opportunities for the student to use constructivism. Proponents of constructivism generally cover far less content than a more traditional approach to teaching chemistry. Very few topics in chemistry do students come to class knowing. Therefore they have little knowledge base to build upon. For these reasons, I will continue to be more traditional and resist constructivism as the only tool to teach chemistry.

To install a wood shelf in your closet, first measure the space and cut the wood to fit. Use a level to ensure the shelf is straight, then mark where the shelf will be placed. Drill holes for the brackets, attach them to the wall, and then place the shelf on top. Use screws to secure the shelf to the brackets.
