Ammonia
>Two important resources of ammonia are ammonium salts and ammoniacal liquor obtained by the destructive destruction of coal . Ammonia and ammonium compounds are highly soluble in water and do not occur as minerals in large quantities. The NH 3 molecule has a..

Lanthanides are chemically reactive. They react with carbon, hydrogen, oxygen and sulphur and form carbides, hydrides, oxides and sulphides respectively. The oxides formed are M 2 O 3 oxides. They react with water and form insoluble hydroxides. The oxides a..
Chemical Equation
. Initially, write the word equation, and below it, write the molecular equation. Example 1: This is an unbalanced equation, because, in the reactant side, there are 2 atoms of oxygen, but on the product side, there is only one atom of oxygen. Since the number of atoms of all the particip..
Chemical Properties of Water
Chemical Properties of Water - 1. Metals such as gold, silver, copper, tin, etc. do not react with water. 2. Ordinary iron gets rusted and aluminium gets tarnished. 3. Highly electro-positive metals react vigorously with water to form their respective hydroxides..

Some Important Chemical Compounds Summary
Summary - Common name Chemical name Formula Washing soda Sodium carbonate decahydrate Na 2 CO 3 .10H 2 O Baking soda Sodium bi carbonate NaHCO 3 Quick lime Calcium oxide CaO Bleaching powder Calcium oxychloride CaOCl 2 Slaked lime Calcium ..
Balancing of Chemical Equations
If the number of atoms of an element on both sides of a chemical reaction is equal, then the equation is said to be balanced . Example: Potassium nitrate decomposes on heating to form Potassium nitrite and Oxygen. Now count the number of atoms of each element on each side of the eq..
Balanced Chemical Equations
It does not give any idea about colour changes, which has to be mentioned separately. It does not give any indication regarding the production or absorption of heat. This is mentioned separately. C + O 2 CO 2 + Heat C + CO 2 2CO - Heat Some reactions are reve..
Thermal-Chemical Effects of Currents Summary
Summary - If a current I flows through a potential drop V, the energy lost per second by the drifting charges is VI. In a resistor of resistance R, the loss of energy appears as heat. The rate of heat production P is P = VI = I 2 R = V 2 /R and is independent of the direction of..
3. SINGLE DISPLACEMENT REACTIONS
This is a reaction in which an atom or a group of atoms present in a molecule gets displaced by another atom. a) Displacement of a less active metal by a more reactive one i) When a piece of iron is added to a solution of copper (II) sulphate, iron displaces copper from copper sulphate...
