Question

Cuántas moles de ZnCl2 y de H2 se forma a partir de 1.5 moles de Zn?

Answer 1

                  Zn + 2HCl  → ZnCl2 + H2↑
a.

n H2 = 1.5 mol Zn  x    1 mol H2
                                   ````````````````
                                     1 mol Zn

n H2 = 1.5 mol

b.

n ZnCl2 = 1.5 mol Zn x 1 mol ZnCl2
                                      ````````````````
                                        1 mol Zn  

n ZnCl2 = 1.5 mol
