chemical formulae for calcium nitride

When steel (containing 1% of aluminium) is heated in an atmosphere of ammonia at 550 o C - 600 o C, the surface of steel becomes very hard. This is called nitriding . Nitrogen formed by the dissociation of ammonia reacts with iron and aluminium to form the respective nitrides on..

The electronic configuration of magnesium is 2,8,2 and that of nitrogen is 2,5. A magnesium atom needs to lose two electrons, whereas the nitrogen atom needs to gain three electrons to attain the octet. The chemical formula for magnesium nitride is Mg 3 N 2 . ..

It is fifth most abundant element in Earth's crust. It is found existing as whole mountain ranges of limestone, marble and chalk, in vast sedimentary rocks of CaCO 3 . Other important minerals containing calcium are gypsum (CaSO 4 .2H 2 O), anhydrite (CaSO 4 ), fluorite (CaF 2 ) and fluo..

It is absorbed as Ca 2 + io..

Hydrolyzing metal nitrides like magnesium and aluminium nitrides, with water or alkalies, can also produce ammonia gas. ..

Reactants are written on the left side separated by + signs. Products are written on the right, also separated by + signs. ' D ' (the greek capital letter delta) placed over or below the arrow means that heat was added to the reactants. (g) means that the substance is gaseous. (l) means that the su..

On hydration, quick lime forms slaked lime or lime water. When water is added to lime it becomes hot and cracks to form a white powder. This is called slaking of lime. Calcium oxide is a basic oxide. It can react with acids to give calcium salts. With acidic oxides lik..

A chemical equation is a "balanced account of a chemical transaction." In any chemical transaction or reaction, the number of atoms of all the participating elements will remain proportionately constant before and after the reaction (The Law of Conservation ..

Calcium hydroxide is obtained as white precipitate when sodium hydroxide is added to a concentrated solution of calcium chloride...
