For the alkali metals, amalgamation is exothermic, and distinct chemical forms can be identified, such as KHg and KHg 2. [4] KHg is a gold-coloured compound with a melting point of 178 °C, and KHg 2 a silver-coloured compound with a melting point of 278 °C. These amalgams are very sensitive to air and water, but can be worked with under dry ...
Amalgamation (race), a now largely archaic term for the merger of people of different ethnicities and "races" Amalgamation, another name for a trade union, chiefly used in the UK; Amalgamation, in C (programming language) (C) and C++ programming, merging all the source codes of a library into a single header file
Synthesis of sodium amalgam. Sodium amalgam, with the common formula Na(Hg), is an alloy of mercury and sodium.The term amalgam is used for alloys, intermetallic compounds, and solutions (both solid solutions and liquid solutions) involving mercury as a major component.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
This amalgamation can continue well beyond the vulnerable aluminium that was exposed, potentially reacting with a large amount of the raw aluminium before it finally ends. [ 5 ] The net result is similar to the mercury electrodes often used in electrochemistry , however instead of providing electrons from an electrical supply, they are provided ...
Zinc amalgam is a solution of zinc in mercury. In practice the term refers to particles of zinc with a surface coating of the amalgam. A gray solid, it is typically used for reduction.
For example, when a more conservative preparation would be beneficial, composite is the recommended restorative material. These situations would include small occlusal restorations, in which amalgam would require the removal of more sound tooth structure, [ 32 ] as well as in "enamel sites beyond the height of contour". [ 33 ]
A commutative diagram of the amalgamation property.. In the mathematical field of model theory, the amalgamation property is a property of collections of structures that guarantees, under certain conditions, that two structures in the collection can be regarded as substructures of a larger one.
