Materials- Metals &Non-metals

Oxidation React with oxygen to form basic oxides

Reaction with Water React with water to liberate hydrogen and form alkali

React with acids to liberate hydrogen and form the respective metal salt

Metals like Aluminium react with alkalis to liberate hydrogen gas and from the respective salt

Some metals displace other metals from their salt solution
