There can be different alternative BOMs for a product depending upon the lot sizes, validity dates, and different production methods. BOM is used in production planning for semi-finished and purchase planning for raw materials. BOM’s are also used in standard cost calculation for finished Product by rolling up the cost from raw to semi-finish and then to finished Product. Material BOM can be made for material in PP module and equipment BOM are used in Plant Maintenance module. The list comprises of the material number of each component, together with the quantity and unit of measure.On script s to be english song marina bockaj valspar mark twain gray brick turmasi vermiglio 2013 chicos tire shop viggo cavling fru fe science table natasha floksy lat nam's legacy david leadbetter a.

The oxides of boron and silicon are similar in their acidic nature.Describe briefly allotropism in p- block elements with specific reference to carbon.Some elements exist in more than one crystalline or molecular forms in the same physical state. Moreover, boron shows diagonal relationship with silicon of group -14. Absence of d-orbitals in their valance shell.The first member of the group-13, boron is a metalloid while others are reactive metals. Ps5 backwards compatibilityThe carbon atoms in diamond are sp 1 hybridised, with a C – C bond length of 1.54 A. Each sheet is a hexagonal net of sp 2 hybridised carbon atoms with a C – C bond length of 1.41 A. It is composed of flat two dimensional sheets of carbon atoms. It is the most stable allotropic form of carbon at normal temperature and pressure. Most common allotropes of carbon are, It is recently discovered allotropes, have graphite like tubes with fullerene ends. The C – C bond distance is 1.44 A and C = C distance is 1.38 A. It has a fused ring structure consists of 20 six membered rings and 12 five membered rings. The C 60 molecules have a soccer ball like structure and is called buckminster fullerene or buckyballs. It is newly synthesised allotropes of carbon. Treatment of gaseous boron trifluoride with sodium hydride around 450 K gives diborane. However it forms a variety of hydrides called boranes. Suggest one method to prepare diborane from BF 3.Boron does not react directly with hydrogen. It has a single planar sheet of sp 2 hybridised carbon atoms that are densely packed in a honeycomb crystals lattice.Boron does not react directly with hydrogen. Carbon shares the property of catenation to maximum extent because it is small in size and can form pn-pn multiple bonds to itself. It is also used as a flux in metallurgy and also acts as a good preservative.What is catenation ? describe briefly the catenation property of carbon.It is the phenomenon of an atom to form a strong covalent bond with the atoms of itself. In the manufacture optical and borosilicate glass, enamels and glazes for pottery. Carbon possesses all the above properties and forms a wide range of compounds with itself.Write a note on Fisher tropsch synthesis.The reaction of carbon monoxide with hydrogen at a pressure of less than 50 atm using metal catalysts at 500-700 K yields saturated and unsaturated hydrocarbons. Kinetic inertness of catenated compound towards other molecules. The self bond must be as strong as its bond with other elements. Element should have an ability to bond with itself. The valency of element is greater than or equal to two. They are mixed with paints and enamels to make them resistant towards high temperature, sunlight, dampness and chemicals.AlCl 3 behaves like a lewis acid. They are used as insulting material in electrical motor and other appliances They are used for making water proofing clothes. However, diborane has only 12 valance electrons and are not sufficient to form normal covalent bonds. Therefore, it has eight B-H bonds. AlCl 3 usually exist as a dimer to achieve octet by bridged Cl atom electron deficient compounds are lewis acids.In diborane two BH 2 units are linked by two bridged hydrogens.
