Because it turns into gas
The balanced reaction between Zn and HCl is as follows:
Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g)
This means that HCl would be the limiting reactant.
CuFeS<span>2 chalcopyrite
M(</span>CuFeS<span>2)= 2*63.5+55.8+32*2= 246.8 kg/kmol
3710kg*1kmol/246.8 kg= 15.0 kmol </span>CuFeS2
in 15.0 kmol CuFeS2 is 15.0 kmol Cu
15.0 kmol Cu*63.5kg/1kmol=953 kg Cu
