With hydrogen - When hydrogen is passed through boiling sulphur, both hydrogen and sulphur combine to form hydrogen sulphide (Fig.13.28..

Introduction - Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for s..

Summary - An electrolyte is a compound (salt, acid or base), which in solution or in a molten state conducts an electric current and is simultaneously decomposed by it Electrolytes are ionised into electrically charged ions, which carry the current Charged ions move towards the oppositely charged e..

. These developments indicate a gradual change in the life style of mankind. Today metals are so vital to the modern man that it is unthinkable to live without them. They are essential for the construction of houses, transportation, communication, electricity, household articles, scientific instrum..

Question 1 - Question: Compare the properties of a typical metal and a non-metal on the basis of the following. Fill in Column A, B. Properties A Metal B Non- metal Electronic configuration ? ? Nature of oxides ? ? Oxidizing or reducing action ? ? Conduction of heat an..

Nitric acid is a strong oxidizing agent. When it undergoes thermal decomposition, it yields nascent oxygen as follows: ..

Hydrogen is a combustible gas, but does not support combustion. In presence of air or oxygen it burns with a blue flame to form water. If hydrogen is mixed with oxygen, it explodes with a pop sound. A Jet of Hydrogen Burns in Air with a Pale-blue Flame. The Steam is Condensed to Water on ..
