Do you mean mercury sulphite?

Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg (from the Latinized Greek hydrargyrum, for watery [or liquid] silver) and atomic number 80. A heavy, silvery transition metal, mercury is one of five elements that are liquid at or near standard room temperature (the others are the metals caesium, francium, and gallium, and the nonmetal bromine). Mercury is used in dental amalgam as well as thermometers, barometers and other scientific apparatus, although the use of mercury in thermometers has been largely phased out in clinical and scientific environments (in favor of alcohol-filled, digital or thermistor-based replacements) due to concerns about the element's toxicity. Mercury is mostly obtained by reduction from the mineral cinnabar.

it is also dangerous like mercury.Be carefull when you use it.\nWhen you touch the mercury you might get poisoned.Mercury not only dangerous via mercury vapour.

Don't have it handy,but it'sjust a little denser than water, from what I remember. Check www.nasa.gov. They have lots of planetary info!

Spin relative to what?\n\nThe spin of the Earth about its own axis causes day and night but only because the spin is not synchronised with the orbit of the axis around the sun.  Mercury spins once on its axis for every orbit and so always has the same face to the sun.  It could be said in this case that Mercury does not spin, but that is only relative to the orbit of Mercury.\n\nImagine a frame of reference that is fixed in space like the grid lines on a map.  If a planet did not spin on its axis relative to this reference, then it would have a day/night cycle that took one orbit to complete (this would be one year for the Earth).\n\nIt is also believed that the spin of the Earth contributes to the generation of the magnetic field, so if the spinning stopped or slowed (relative to any reference) we could loose the magnetic field and thus be exposed to higher radiation levels from the sun.

Mercury is the only common metal liquid at ordinary temperatures and rarely occurs free in nature.  \n\nIt is a heavy, silvery white metal; a rather poor conductor of heat, as compared with other metals, and a fair conductor of electricity.  It easily forms alloys with many metals, such as gold, silver and time which are called amalgams.  \n\nThe metal is widely used laboratory work for making thermometers, barometers, diffusion ion pumps and many other instruments. Mercury should be handled with care because of the absorbing through the skin and can cause many problems (very serious ones).

It's funny you asked that today because there was a mercury spill here at my school yesterday. A 2"x2" "puddle" was found so the building and the building next door have been quarantined and anyone who traveled through recently has to go to public safety to have their shoes decontaminated. \nAs I understand, Mercury is harmful if consumed (most commonly in water or freshwater fish), if it comes in contact with skin (because it is absorbed, not because it will harm your skin superficially), if breated in (it is in emissions from manufacturing, burning coal for fuel, or from volcanoes), or, according to some people, if it is absorbed from amalgams used in dentistry (like metal fillings). The most harmful form of mercury is that which is breathed in.

float as mercury has a density of about 13.6gm/cc and iron much lesser 7.85gm/cc. Mass is immaterial as  in a sufficient quantity of mercury even a 1000000000000kg iron ball will float

Ammoniated mercury is an effective material for dermalogical cases ,how ever if th econcentrationis more than the therapeutic need it may be absrbed by the skin and cause mercury poisining

Technically, you really want to know which has more mass (greater gravitational effect), or which has greater density.  Earth by far has more mass, and is far larger.  On the other hand, they are very close in average density.  The average density of Earth is 5.515 g/cm^3 (the densest planet in the solar system), the average density of Mercury is 5.427 g/cm^3 (#2).\n\nThe reason for this is quite interesting.  Like Earth, Mercury has an iron rich core, which means that early in its life Mercury separated out into the heavy dense metals and lighter rocks.  The light stuff floated to the top and became the crust, and the heavy stuff sank to the middle and became the core, just like Earth.\n\nIt seems, though, that sometime early in Mercury's history is collided with a huge planetesimals.  The collision stripped away almost all the crust, sending it into the sun and to the outer planets (Venus and Earth).  It was a cataclysmic collision, destroying the planet that was Mercury and leaving barely more than the core, which is what there is now.  Mercury used to be about 2.5 times bigger than it is now, bigger than Mars and rivaling Earth and Venus.  But because of that collision, little more than the core remains, which is why it is so dense.

Something more powerful than the Sun's gravitational influence on Mercury.

This is sort of true, but not entirely. Mercury has a very fast orbit around the sun, and a very slow rotation about its axis - in fact, the "days" are longer than the "years."  Additionally, Mercury's orbit is very erratic - sometimes it gets really close to the sun, and other times it gets further away.  During the times when its orbit is getting closer to the sun, the gravity acting on it makes it speed up.  When the planet speeds up then the relative speed of the planet's orbit and its rotation change.  The result is that the sun would appear to rise about halfway, go back down again, and then start rising and setting normally.  This happens only in the eight or so Earth days around "perihelion" - the time when Mercury is closest to the sun.

um, no. It's not mercury. Liquids can mean any liquid, not just a periodic element. Lauric Acid has an atomic mass of 280g/mole, which is OVER any element by itself and it's melting point is at *negative*16 degrees Celsius. Long fatty chains like vegetable oils are in multiples of that.

Planetary composition\nJupiter is composed of a relatively small rocky core, surrounded by metallic hydrogen, surrounded by liquid hydrogen, which is surrounded by gaseous hydrogen. There is no clear boundary or surface between these different phases of hydrogen; the conditions blend smoothly from gas to liquid as one descends.\n\nhttp://en.wikipedia.org/wiki/Jupiter#Planetary_composition\n\nwikipedia strikes again!
