Mercury is an element and a metal that is found in air, water, and soil. It exists in three forms that have different properties, usage, and toxicity. The three forms are calledelemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. Elemental mercury is li...
What are the uses of a mercury barometer? Discuss how water can effectively extinguish oxidizer-supported fires. Why does water light on fire? What is mixed with it that is combustible? What element is used in thermometers? What are the technological benefits of chemistry?
It is an electronic balance that uses a mechanism of electromagnetic force compensation to balance the load on the pan. Another type of analytical instrument is analytical glassware that has a higher precision and more accurate demarcations for measured volumes. Burette...
Dropping point definition: The dropping point (DP) is a characteristic property of a material. Samples are heated until they transform from a solid into a liquid state. The dropping point is the temperature at which the first drop of a molten substance precipitates from a standardiz...

What are the symptoms of mercury poisoning? The exact symptoms of mercury poisoning vary depending on the type of mercury and method of exposure. When high amounts of methylmercury are consumed, they can cause a type of poisoning known as Minamata disease. This manifests itself in the shape ...
Uses for Mercury Mercury conducts electricity and is used in a variety of devices, such as: •thermometers •barometers •batteries •reed switches The gas form of the element is used in mercury-vapor lamps, and mercury is also used in the production of pesticides and other chemicals. ...
