Describe how a mercury barometer measure air pressure?
The basic principle of barometer is Torricelli's experiment. Imagine that you fill a tube of one metre length (100cm) with mercury up to the brim. Then close the mouth of the tube with your thumb and invert the tube and place it in a cistern of mercury with its end immersed in the mercury say some 4 cm. Now you remove your thumb. Mercury would come down but it stops at one level to our astonishment. This level would be some 20 cm from the closed end of the tube. So there will be almost 76cm column of mercury in the tube. Why is it so? As mercury comes down the space left vacant will not be having any air molecule and so it is almost vacuum. This is named as Torricelli's vacuum. Now the air outside in the atmosphere would exert a pressure and wants to push the mercury towards this vacuum place. But the weight of the mercury column (76cm) will balance this pressure. Hence we say the atmospheric pressure will be 76 cm of mercury. This is how we have mercury scale for measuring the pressure. Usually pressure is defined as the force per unit area. Hence the unit will be N/m2 or pascal. But we give pressure only in cm or mm of mercury. The reason is explained properly. Same technique is applied in Fortin's barometer and vernier arrangement is made to measure the pressure so accurately.
Is a water molecule larger than a oil molecule?
no
Its mercury a diatomic molecule in nature?
No

Is mercury a molecule or atom?
Mercury, as in Hg is an element. It is a metal, in the transition metals, that, when in an ionic bond, holds a +2 charge - making it a cation. Or, if pertaining to astronomy, Mercury is a planet in our solar system. It is the one closest to our sun.
Mercury has a higher density than water.Does the molecules of mercury is heavier than molecule of water?
Scientists found out and then proved it.
Does the molecules of mercury is heavier than molecule of water?
If you understand what molecular weight (MW or FW) means, then look at the molecular weight of one molecule of mercury (Hg2) and compare that to the molecular weight of an H2O molecule.Which is heavier?
Is Hg an atom or molecule?

How many atoms in HgCl2?
2Hg atoms and 2Cl atoms for a total of 4 atoms.
How many electron shells does mercury have?
There are two valence electrons in a mercury molecule. Mercury is known commonly as quicksilver. It is also registered as the symbol Hg.
How many atoms in mercury(1) sulfate?
In the formula unit for mercury (I) sulfate, there are two atomic symbols for mercury, one atomic symbol for sulfur, and four atomic symbols for oxygen. This gives a total of seven total atoms.
The elements that exists as monoatomic molecule?
Helium, neon, argon, krypon, silver, xenon, gold, mercury, radon and ununoctium.
Can sodium and mercury exist in monoatomic molecule in vapour state?
No, sodium and mercury exist as diatomic molecules in the vapour state due to the nature of their chemical bonding. Sodium forms Na2 while mercury forms Hg2 molecules.
Is Hg pure substance a homogeneous mixture or a heterogeneous mixture?
Pure Substance.Hg stands for mercury. A pure substance is made of only one type of atom or molecule. Since mercury is an element, it is a pure substance.
