Which is the correct one? Or are both of them the same?
Zn0 + Na0H= Na2Zn02 + H20
and
Zn0 + Na0H= [Zn(OH)4]2- + 2 Na+
and pliz gimme the reason why ok?
thanks
Apart from the fact that the equations aren't balanced, you need to state whether you are working in aqueous solution (that would be b) or in a melt (a).

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.

Wide band gap semiconductor Zinc Oxide is of significant interest for use in blue LEDs, short wavelength laser diodes, high temperature and power devices, and transparent conductive oxides. Polar caxis oriented Zinc Oxide and its alloy Magnesium Zinc Oxide based heterostructures and quantum wells have been developed. These heterostructures and quantum wells however suffer from limited quantum efficiency due piezoelectric and spontaneous polarization fields. The use of nonpolar aaxis and maxis oriented films has thus gained importance for development of high quantum efficiency structures. The nonpolar films however possess inplane structural, optical, electrical and acoustic anisotropic properties. Though some of these properties maybe advantageous for development of novel electronic, optical and acoustic devices, others might be detrimental to development of nonpolar heterostructures and quantum wells. Currently, only limited information is available of study and control of these anisotropic properties. This book presents MOCVD growth optimization and comprehensive characterizations of anisotropic properties of aplane Zinc Oxide and Magnesium Zinc Oxide thin films.

High Quality Content by WIKIPEDIA articles The zinczinc oxide cycle or Zn/ZnO cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production with a typical efficiency around 40. For the first endothermic step concentrating solar power is used in which zinc oxide is thermally dissociated at 1,900 C (3,452 F) into zinc and oxygen. In the second nonsolar exothermic step zinc reacts at 427 C (800.6 F) with water and produces hydrogen and zinc oxide. The temperature level is realized by using a solar power tower and a set of heliostats to collect the solar thermal energy. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Reader of scientific magazines should know that zinc act as a metallic chemical element and commonly known as spelter. Zinc carries the symbol Zn . The properties of zinc is same as of magnesium in terms of ion size and oxidation state. And the most common zinc ore found in the nature is sphalerite known as zinc sulfide. The biggest deposits of zinc is australia, canada, and united states. There are several process involve in the production of zinc such as froth flotation, roasting, and extraction. All this process done with the help of electricity.
One should understand the fact that for exceptional biologic and public health importance zinc act as very important mineral. One should not take the risk of having zinc deficiency as it might lead to growth retardation, delaying sexual maturatity, infection susceptibility, and diarrhea . Around two billion people get affected across the globe. One should strictly take c are that even by mistake one should not consume zinc leading to ataxia, lethargy, and copper deficiency. Users of zinc very well knows that zinc also taken as spelter in nonscientific fields.
Zinc is a very bluish-white, lustrous, and diamagnetic metal. Zinc is quite less dense in comparison to iron carries hexagonal crystal structure. In industries where alloy consumption is more, found to have the prescence of zinc in these alloys such as brass is a alloy of zinc and copper. Besides this there are binary alloys who make the usage of zinc such as aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium and sodium etc. Globally zinc resources on the earth is around 1.8 gigatonnes. Mostly one will find zinc deposits in australia, canada and united states etc.
