The balanced chemical equation for the reaction of zinc metal with hydrochloric acid is:
Zn + HCl → ZnCl + H2
Zn + HCl → ZnCl2 + H2
Zn + 2HCl → 2ZnCl2 + H2
Zn + 2HCl → ZnCl2 + H2
Number of atoms of each element are equal on both sides in the balanced equation.
Is this right :
2Zn+2Hcl Will give 2ZnCl + H2
Zn reacting with hcl
X+HCl→ZnCl2+H2O+CO2
Find X and balance the equation.
To prepare 1 g of hydrogen molecules using hydrochloric acid how many grams of zinc should be taken?
Zn +2HCl ------>ZnCl2 + H2
