Magnesium nitride

▶ Magnesium nitride (Mg3N2) powder of high quality has been synthesized successfully through the direct nitridation reaction of Mg powder with N2 gas in 1.0 l/min for 60 min at a nitridation temperature between 650 °C and 800 °C.

Ans: The chemical formula for magnesium nitride can be written as Mg3N2. The entire structure of magnesium nitride is basically formed with the help of 3 magnesium cations which can be denoted Mg2+ and there is also the presence of 2 different Nitrogen (III) anions as well which can be denoted N3-.

Silver nitrate

Copper(II) nitrate, Cu(NO3)2, is an inorganic compound that forms a blue crystalline solid. Anhydrous copper nitrate forms deep blue-green crystals and sublimes in a vacuum at 150-200 °C. copper(II) nitrate (anh.)

Both are blue crystalline solids. Used in medicine, as an insecticide, in chemical analysis, in making light sensitive papers. Toxic oxides of nitrogen are produced in fires involving this material. Copper(II) nitrate is an inorganic nitrate salt having copper(2+) as the couterion.

Copper hydroxide nitrate

(c) The base, Cu(OH)2, is an insoluble base.

Copper carbonate

Sodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O.

Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO3. At ambient temperatures, is an ionic solid (a salt) consisting of copper(II) cations Cu2+ and carbonate anions CO32-.

Pale green

Copper is a reddish brown color that resembles the metal copper.

Copper(II) sulfate

Copper chloride appears as a yellowish-brown powder (the anhydrous form) or a green crystalline solid (the dihydrate).

Zinc chloride is the name of chemical compounds with the formula ZnCl2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. This white salt is hygroscopic and even deliquescent.

Manganese oxide

Manganese(II) chloride

Manganese dioxide (MnO2) is an inorganic compound. It is a black to brown-colored material that occurs naturally as the mineral pyrolusite (see Figure 1).

MnO2 is primarily used as a part of dry cell batteries: alkaline batteries and the so-called Leclanché cell, or zinc–carbon batteries. For this application approximately 500,000 tons are consumed annually. Many industrial uses include the use of MnO2 in ceramics and glass-making as an inorganic pigment.

Manganese dioxide catalyzes the decomposition of hydrogen peroxide to oxygen and water. Since manganese dioxide is a catalyst, it is not consumed in the reaction.
