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 a rule of safety in chemistry: to remove any micro-drops of water from the pipette.
Do all dish washing detergents produce same amount of bubbles?
No.
Can a blimp filled with carbon dioxide float?
It can, if you fill the balloon with air and let it float on the carbon dioxide. We used to do this with soap bubbles to illustrate certain effects of surface tension (for example, the fact that bubbles of the same size form a planar interface, but the interface between bubbles of different sizes bulges towards the larger bubble, proving the pressure in the smaller one is higher... it's much easier to see this when the bubble isn't actively falling towards the floor as you're trying to observe it). Put a piece of dry ice in the bottom of a large bath jar, and allow the bubbles to float on the denser carbon dioxide layer in the jar. Filling a balloon with carbon dioxide, though, will not cause it to float, as carbon dioxide is denser than air.
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

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
Which object despite filling it up can't contain water?
strainer
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?
Sweet pies have a sweet filling and a sweet pastry. (i.e the filling and pastry contain sugar). Savory pies do not.
A small glass vial that is seal after filling and used chiefly as a container for a hypodermic injection solution?
Ampule
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.
Why do I have bubbles in my cake mix?
Sour dough mix is loaded with yeast. Yeast produces carbon dioxide and alcohol as it digests the sugar in the batter. The gluten in the batter allows the carbon dioxide bubbles to form a persistent foam.
What are hydrothermal gold deposits?
The deposits are implaced in veins by magmatic solution, hot water coming up from the depths, filling previously faulted rock.
What is a iron filling?
Iron filling is a filling which can be made by iron filling
