![\large \underbrace{ \underline{ \sf Displacement \: reaction}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cunderbrace%7B%20%5Cunderline%7B%20%5Csf%20Displacement%20%5C%3A%20reaction%7D%7D)
The reaction in which more reactive element replace a less reactive element from its compound is called displacement reaction.
Ex:-
![\bold{\large Zn+HCl \longrightarrow ZnCl_2+H_2}](https://tex.z-dn.net/?f=%5Cbold%7B%5Clarge%20Zn%2BHCl%20%5Clongrightarrow%20ZnCl_2%2BH_2%7D)
Density = (mass) / (volume)
Density = (17.0 g) / (25.3 cm³) = 0.672 gm per cm³. (rounded)
