Mam Can you tell what is displacement reaction

[@MagnetBrainsEducation]

Hey there! Thanks for watching our video and leaving a comment! The displacement reaction is when one element replaces another element in a compound. For example, when iron rusts, the element oxygen takes the place of the element iron.

[@snehakumari2465]

Miss I have a doubt that You told copper reacts with water ,CO2& Oxygen to form greenish coating .that equation is Cu+H2O+CO2+O2=CU(OH2)+CuCO3. Then after this you told lead, copper,gold& silver do not show reaction with water . But to make copper hydroxide we need water & for this copper must react with water.

Mam what' is density

[@MagnetBrainsEducation]

We are glad that you are enjoying our videos and finding them helpful. Density is the amount of mass per unit of volume.
