Which is the correctly balanced equation for a reaction of aluminium sulfide and zinc? Group of answer choices

This reaction is not able to take place.

Zn + Al2O3-> Al + ZnO

3Zn + Al2O3-> 2Al +3ZnO

Zn + Al2O3- Al2 + ZnO3

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
