The Reactivity Series of Metals - Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greater the ease..

. Any atom with this configuration will be in the minimum state of energy, hence stable. Atoms try to attain the octet or the duplet configuration by either loss or gain of electrons. Metal atoms tend to lose electrons. Non metal atoms tend to gain electrons. Example: Lithium ha..

Physical Properties of Oxygen - Oxygen (or dioxygen) has the following physical properties. Oxygen is colorless, odorless and a tasteless diatomic gas under normal conditions. Oxygen is slightly heavier than air. Its density relative to air is 1.1053. Oxygen is sparingly soluble in water. 30 mL of ..

4) Formation of diethyl ether from ethyl alcohol using concentrated sulphuric acid as catalyst. 5) Hydrolysis of esters in the presence of H 2 SO 4 catalyst. In heterogeneous catalysis, the catalyst is generally a solid while the reactants are gases, although sometimes liquid reactants are used. He..
