chemical properties of metals n non metals

a) With hydrogen - Hydrogen burns in oxygen to form water vapor. A jet of hydrogen is burnt in oxygen, in an inverted funnel, as shown in figure (Fig.13.10). The product obtained, is sucked out through a test tube, kept immersed in cold water. The vapor condenses in the test tube to form wate..

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

A detailed comparison of properties of metals and non-metals is given in table. Property Metals Non-metals State of matter These are usually solid, except mercury, which is a liquid at room temperature. Gallium and Caesiu..

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..

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..

Chemical Properties of Sulphur - With Metals - With most of the metals the reaction of sulphur is highly exothermic. Sulphur combines with metals under varying conditions of temperature to form the respective sulphid..

Metals are Electropositive Elements Metals are very reactive. Metals tend to loose electrons easily and form positively charged ions; therefore metals are called electropositive elements. Sodium metal forms sodium ions Na + , Mg forms positively c..
