Question

5 metals with their physical and chemical properties and uses

Answer 1

1)copper
uses: conductor of electricity so used in making wires and alloys like brass
chemical property:gets corrodes when exposed to moist air
physical property: ductile,good conductor,dense
2) aluminum
uses:used in making electric wires,drink cans , alloys like alnico
physical property: lustrous,dense,malleable,good conductor
chemical property: aluminium objects lose their shine after some time as the formation of aluminum oxide takes place when exposed to air
3)iron
uses: making building,car parts ,ships etc
chemical:corrodes and forms rust
physical: lustrous,dense,malleable,ductile,tensile strength
4)mercury
uses:used in thermometer
physical:lustrous,non malleable and ductile
chemical;:reacts with acids to form acidic oxide
5)lead
uses:in batteries and lead pipes
chemical: react with water,dilute mineral acids
physical:non malleable and ductile,lustrous

all metals react with oxygen to for basic oxides and with water to form hydroxide and release oxygen and react with acids and salts also in salts displacement reaction takes place.
