Question

Rakesh was doing an experiment with Magnesium and dil. Hydrochloric acid. He Added Mg cube to 5ml dil. HCl in beaker 1 and Mg powder to 5ml dil. HCl in beaker 2 and observed that the product MgCl2 is formed first in beaker 2. Give. reason.

Answer 1

hiii mate✌️

hope this help❤️

this is because for reaction the compound must be in solvent

Answer 2

This is because powdered Mg gets dissolve and reacts with HCl faster because of small sized particles which has a little less forces of attraction between its particles as compared to a solid whereas Mg cube is a strong solid which has strong forces of attraction between ots particles, so it doesn't reacts readily with HCl.
