When filling the burette why must the solution fill the tip of the burette below the burette tap-and contain no air bubbles?

Because we need to know the exact volume of the solution (and so the amount of the titrant).

Why ist necessary to rinse the clean burette before filling it with the unstandardised sodium hydroxide solution?
It is important to rinse the clean burette to remove any residual contaminants or impurities that could affect the accuracy of the titration results. Additionally, rinsing helps to ensure that the burette is properly conditioned for the new solution being used. This step helps to avoid any potential errors or inaccuracies in the titration process.
How to clean a burette before fill it with hydrochloric acid?
To clean a burette before filling it with hydrochloric acid, rinse it thoroughly with distilled water to remove any impurities or residues. Follow this by rinsing with a small amount of the acid itself, disposing of it properly. Repeat this rinsing process until the burette is clean and ready for use.
Do all dish washing detergents produce same amount of bubbles?
No.
What is a liquid filling machine used for?
Liquid filling machines typically use pressure-overflow fillers, which have a very fast fill rate and can handle a wide range of viscosities. Any leftover product in the filling tubes gets pushed back into the tank, preventing overflow and spillage
How would you justify the presence of 18 elements in the fifth of period of periodic table?
In the fifth period of the periodic table, the atoms of the elements in the first two groups are adding 1 and 2 electrons, respectively, to their highest energy 5s sublevel. Starting in group 3/IIIB and going through group 12/IIB, the atoms of those elements are adding electrons to their highest energy 4d sublevel. Since the d sublevel can contain a maxium of 10 electrons, there are 10 elements whose atoms are filling the 4d sublevel. Once the 4d sublevel is filled, the next higher energy sublevel is the 5p sublevel. Starting with the group 13/IIIA elements, the 5p sublevel is being filled. Since a p sublevel can contain a maximum of 6 electrons, there are six elements whose atoms are filling the 5p sublevel. 5s sublevel filling: 2 elements 4d sublevel filling: 10 elements 5p sublevel filling: 6 elements --------------------------------------- Total: 18 elements For a printable periodic table that includes electron configurations, go to the following link: http://www.nist.gov/pml/data/periodic.cfm

How to handle burrete AND PIPETTE correctly?
To handle a burette correctly, ensure the stopcock is closed when filling the burette and open when dispensing liquid. For a pipette, use a pipette filler to draw liquid into the pipette and dispense by pressing the filler gently. Handle both instruments with care to prevent breakage or spills.
Is there a filling you can use at home for a tooth?
You can usually buy temporary filling kits from the chemist/pharmacy but they are not a permanent solution.
Is powdered sulfur and iron filling a mixture or a solution?
a mixture
What uses a funnel?
A funnel is used to help pour liquid from one container to another without spilling. I use a funnel when pouring oil back into a bottle for storage, or when filling a burette from a small reagent bottle.
What household items contain krypton?
Krypton is used as a filling gas for energy-saving fluorescent lights and as an inert filling gas in incandescent bulbs.
What is the difference between sweet pies and savory pies?

What is the filling in the chocolate sugar wafers made with?
The filling in the chocolate sugar wafers are made with chocolate and sugar as well as wafers and can also contain peanut and coconut shavings from time to time.
Which object despite filling it up can't contain water?
A sieve or a colander cannot contain water because of the holes that allow liquid to pass through.
What is the solution to a hole INSIDE the tooth?
The solution for a hole inside the tooth, also known as a cavity, is typically a dental filling. This involves removing the decayed part of the tooth and filling the space with a material such as composite resin or amalgam to restore the tooth's structure and function. It is important to address cavities promptly to prevent further damage and potential infection.
