Type 3 binary compound examples
Crucial to the abstract-real-specific substance logic is whether the stuff in question is homogeneous or heterogeneous— whether it is a single phase or has phase boundaries. Chemists love their chemical stuff to be homogeneous: Consider diamond , the well known allotrope of carbon. So the abstract diamond , the allotrope of carbon, notion of diamond is rather different to the notion of real diamond , the synthetic grit used for hardening machine parts or a bag of small colour and sized matched gem stones used by jewelers, and this is rather different to the large specific diamonds , of extraordinary value with individual names.
A s discussed elsewhere in this web book , chemists may attempt the synthesis of a chemical that cannot be made in principle. Such a synthetic target can only be abstract. It is thought hydrogen forms a metallic phase at high pressure, but until proved conclusively the notion of metallic hydrogen is abstract. Ions are abstract entities. Sodium chloride exists, but the sodium ion and chloride ion are imagined. The aluminium ion in water may be represent as: I quickly learned while doing my Ph.
If a proposed reaction fails in the research lab, is it because the reaction scheme is flawed or because the experiment was poorly executed? Is the abstract chemistry wrong or is the real chemistry wrong????? When I first started to develop this project I naively assumed that there would be one entry per chemical , but this soon proved impossible.

Leach, the author, using mrl meta-synthesis. This free, open access web book is an ongoing project and your input is appreciated. Definition of Binary Compound Dictionary and web definition of a binary is: We are interested in the sub-set of binary compounds that are: Many binary compounds fail our strict one-type-of-strong-chemical-bond requirement. For example, there are literally thousands of hydrocarbons substances consisting of hydrogen and carbon only including: But only methylene, CH 2 , and methane, CH 4 , possess only one type of strong chemical bond and are the only substances to be considered binaries, here.
Water , H—O—H, only has hydrogen-to-oxygen bonds, whereas hydrogen peroxide , H—O—O—H, has hydrogen-to-oxygen and oxygen-to-oxygen bonds. The chemical elements as material substances are here — within the Chemogenesis web book — considered to be special case binaries where the two elements are identical: This definition also holds with bulk elemental materials: A compound in whcih electrons are shared equally or unequally between two atoms forming a bond.
Representative Metal with fix charged. Magnesium oxide Ag 2 S: Cadmium nitrate NH 3 2 SO 4: Generally a transition metal. Any metal not type I. Order of name and formula are: Binary compounds, Ternary compounds, Ionic compounds, Covalent compounds Binary compounds: Ionic compounds in which the cation has a fix charge. Silver sulfide Cation - Anion Example: Ammonium sulfate Type II: Ionic compound in which the cation has a variable charge.
