if 2.0 mol of HF are exposed to 4.5 mol of SiO2,which is the limiting reactant?SiO2(s)+4h=HF(g)→SiF4(g)+2H2O(I)
if 2.0 mol of HF are exposed to 4.5 mol of SiO2,which is the limiting reactant?
SiO2(s)+4h=HF(g)→SiF4(g)+2H2O(I)

if 2.0 mol of HF are exposed to 4.5 mol of SiO2,which is the limiting reactant?SiO2(s)+4h=HF(g)→SiF4(g)+2H2O(I)
HF is the limiting reactant
