Metal Oxide

If the oxide contains 28.53% O by mass, what is the identity of the metal?

A metal (M) forms an oxide with the formula MO. If the oxide contains 28.53% O by mass, what is the identity of the metal? Answer as a chemical symbol.

moles O = moles M = 28.53 g/ 15.999 g/mol=1.78
mass M = 100 - 28.53=71.47 g

molar mass M = 71.47/ 1.78=40.1 g/mol

M is calcium

Lithium Oxide $60.54 High Quality Content by WIKIPEDIA articles Lithium oxide (Li2O) or lithia is an inorganic chemical compound. Lithium oxide is formed along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen: 4Li+O2 2Li2O. Pure Li2O can be produced by the thermal decomposition of lithium peroxide, Li2O2 at 450 C 2Li2O2 2Li2O + O2 Structure In the solid state lithium oxide adopts an antifluorite structure which is related to the CaF2, fluorite structure with Li cations substituted for fluoride anions and oxide anions substituted for calcium cations. The ground state gas phase Li2O molecule is linear with a bond length consistent with strong ionic bonding. VSEPR theory would predict a bent shape similar to H2O.

Doped Transition Metal Oxide and Ferrite Nanocrystals $180.02 Nanosized magnetic materials have received great attention and importance during the last decade. Nanomagnetic material is one of the hottest subjects of present day research activities. The physical properties of nanosized magnetic materials differ considerably from that of their bulk counterparts and the magnetic characteristics of many materials can be tuned by reducing their size. The objectives of this research work are the synthesis and studies on the structural and magnetic properties of some selected transition metal oxides and ferrites in nanocrystalline form. The research work has been carried out on transition metal ion doped zinc oxide (ZnO) based diluted magnetic semiconductors (DMSs), some ferrites (for instance, Znferrite, NiZnferrite, maghemite, etc.) and magnetopolymer nanocomposite systems. The respective nanocrystalline oxides are synthesized using a simple solution combustion method and characterized using various techniques. The results from the studies on different materials are presented in this thesis, consisting of six chapters. Last but not the least, several performance parameters have been measured and conditions for best results have been discussed.

Zinc Oxide Eugenol $68.51 High Quality Content by WIKIPEDIA articles Question booknew.svg Zinc oxide eugenol (ZOE) is a material created by the combination of zinc oxide and eugenol (contained in oil of cloves. An acidbase reaction takes place with the formation of zinc eugenolate chelate. The reaction is catalysed by water and is accelerated by the presence metal salts. ZOE can be used as a filling or cement material in dentistry. It is often used in dentistry when the decay is very deep or very close to the nerve or pulp chamber. Because the tissue inside the tooth, i. e. the pulp, reacts badly to the drilling stimulus (heat and vibration), it frequently becomes severely inflamed and precipitates a condition called acute or chronic pulpitis. This condition usually leads to severe chronic tooth sensitivity or actual toothache and can then only be treated with the removal of the nerve (pulp) called root canal therapy. The placement of a ZOE temporary for a few to several days prior to the placement of the final filling usually prevents the sensitivity or toothache and therefore, most times, precludes the need for the expensive and time consuming root canal procedure.

Why You Need Anodizing of Metals

Aluminium alloys are always an excellent choice of metal for home machining. It can be used on mini-lathe to make telescope parts or camera adapters and other helpful bits and pieces. But there is an unfortunate drawback in using aluminium this way. The key advantage and disadvantage of this metal is its relative softness towards other metals such as steel. This supple nature makes it very easier to engine on a mini-lathe than steel, but, if once you have completed your part, it is very liable to tiny dents and surface scratches.

When chemically speaking, aluminium is an awfully reactive metal. We all are familiar with the action of our environment on iron. It will oxidise pretty readily to form iron oxide - or rust as more commonly known. Aluminium is highly reactive than iron, and, so, will rust more readily. Yet, with aluminium a rough coat of aluminium oxide will be formed which strongly inhibit further oxidation of the metal. Due to this aluminium is known for its elasticity in corrosive environments like car radiators or boats. In later period of time aluminium "rusts" - and slowly produce a white powdery coat.

For the aluminum industry there is a system to overcome the inbuilt softness of the metal and protects against oxidation. Using chemical process it is possible to build a layer of aluminium hydroxide on the surface of the metal that is very hard and more durable than the rough naturally oxidised film that normally forms. This process involves suspending the aluminium in acid bath and passing electric current through it. And this is known as anodizing. It is an electrochemical method that works with the porous makeup of the aluminum. This process thickens and toughens the naturally occurring protective oxide. Thus it offers a higher life span to the product. As anodic coating becomes part of the metal, it is one of the hardest substances for metal finishing. Anodizing also adds durability and color stability.

The advantage of anodizing aluminium is the latent of colored anodizing dye. It seeps into the microscopic pores of the anodized part and gives colors to it. This layer is then sealed and the color appears as part of the metal itself. This can generate great artistic effect, making aluminium parts with strikingly tasteless colors to ornament your motor bike or more topically, your telescope. With visual applications, black is the most popular anodizing color inorder to reduce the internal reflections. Of course, black is supposed to be one of the hardest colors to achieve and so the commercial black anodizing dye is fetching the highest price in the market.

Anodizing aluminium is a fairly simple process, and providing you can put your hands on the correct chemicals (sulfuric acid) it is rather straightforward to do simple anodizing aluminium in home. You could limit yourself to anodizing in fairly small amounts - but if you want to anodize a large object you require a lot of electrical power and acid, so if you want to it for an entire bike frame in one go, You can contact an aluminium anodizing company.
