Question

About physical and chemical properties of iron and aluminium

Answer 1

Physical and Chemical propertiy of Aluminum
Th density of aluminum is 2.7 g/mL, which means the metal will sink in water, but is still relatively light. Chemical Properties: The surface of aluminum metal is covered with a thin layer of oxide that helps protect the metal from attack by air. So, normally, aluminummetal does not react with air.


Physical and Chemical propertiy of Iron
Physical and Chemical Properties. Iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white.
