conditions of rusting process

Conditions for Rusting of Iron - The presence of water and oxygen is essential for the rusting of iron. Impurities in the iron, the presence of water vapor, acids, salts and carbon dioxide hastens rusting. Pure iron does not rust in dry and carbon d..

The presence of water and oxygen is essential for the rusting of iron. Impurities in the iron, the presence of water vapor, acids, salts and carbon dioxide hastens rusting. Pure iron does not rust in dry and carbon dioxide free air. It also does not rust..

Rusting of Iron - Who has not seen the damaging effects of rusting of iron! During the process of rusting the oxide that forms is brittle and chips off from the surface. This exposes yet another layer below to the deleterious effects of moisture and air. Thus..

The burning of a substance is called combustion. It is an exothermic process (chemical reactions which give out heat to the surroundings are called exothermic reactions..

Combustion - The burning of a substance is called combustion. It is an exothermic process (chemical reactions which give out heat to the surroundings are called exothermic reactions). E.g., Burning of coal Burning of butane gas (g - gas form) The common observation in the above reactions ..

The manufacture of ammonia by Haber's process involves the direct combination of nitrogen and hydrogen...

This type of reflex involves the brain but it is also as fast as the simple reflex. Salivation on smelling one's favourite food is an example of conditional reflex. The individual recognises the smell and based on a previous experience, the response (salivation) occurs. The recognition of..

The criterion for a chemical change is the production of one or more new substances. Therefore, certain conditions should be met in order to bring about a chemical change. The necessary conditions are: A minimum amount of energy needed to initiate a reaction (activation energ..
