The same as the tests for snake oil. "Red Mercury" is a fictitious substance to which a wide variety of miraculous properties are ascribed. See the link to the Wikipedia article for details, but essentially, it's a scam. (There are several reddish compounds of mercury, such as cinnabar; if you were wanting information about one of those, please ask again using its proper name instead.)
Mercury is an element and therefore a pure substance.
Mercury is an element that is also a liquid. It is in the Periodic Table and is #80.
Density is weight per volume. It does not change because the size of the specimen changed. The total weight will increase, but not the density.
No, electrolytes are those substances which produce ions in solution or in molten form, Mercury is a pure liquid metal and conduct the electricity.
The Mercury Dime contains: 0.900 silver and 0.100 cooper. The net weight of the pure silver in this coin is: 0.07234 oz.
Mercury is highly poisonous - causes madness. Avoid using it at all.
Pure Mercury is homogeneous and is an element, which is a pure substance, and not a mixture. There is little chance that you will encounter pure mercury because it exists only in textbooks. In reality, there are always other impurities mixed and dissolved in the mercury. The liquid mercury obtained from chemical suppliers claims to be at least 99.99% pure. This would be a pure substance, not a mixture, only if it were 100% pure. "Close to pure" is not pure. "Pure" only exists in textbooks.
Mercury is an element and is therefore a pure substance. There are no other elements in it.
Neon. It's actually a sort of orangey-red and not a pure red. Pure red bulbs are probably fluorescent bulbs containing mercury vapor with tinted glass to make the light appear red.
No, mercury is a pure substance.
Mercury exist in pure state in the nature and is known from thousands of years.
The amount of pure Mercury found on earth is relatively low compared to other elements. Finding pure mercury itself in large pools for nearly all purposes is impossible and finding mercury in its pure state (liquid) is also rare. But Mercury is not a rare element because it's found in large amounts. Mostly all mercury is found in its impure state in a red ore called cinnabar (HgS), which is made up of mercury and sulphur. Much of the worlds Mercury in mined in Spain and Italy. though several other countries also produce commercial quantities.
Mercury is an element and therefore a pure substance.
Mercury is a "pure substance" in the sense that is an naturally occuring element on the Periodic Table. However, it can combine with some other elements in nature and so may not be found in its pure form. cinnabar (HgS) is a common form. That's 1 Mercury atom + 1 Sulfur atom.
None, mercury is a pure element.
Not in pure Mercury, it is an element.
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.
