Calculate how many grams of Zinc Chloride are produced if 6.5 of Zn is used to react in the chemical reaction below. Be sure to show all of your work.
Zn + 2HCl —> ZnCl2 + H2

Answer 1

Answer;

= 13.629 g of ZnCl2

Explanation;

The equation for the reaction.

Zn(s)+2HCL(aq)=>ZnCl2(aq)+H2(g)

Number of moles of Zinc;

Moles = mass/RAM

= 6.5 g/65g/mol

= 0.1 moles

The mole ration of Zn : ZnCl2 is 1 : 1

Therefore, number of moles of ZnCl2 is 0.1 moles

Mass = moles × Molar mass

= 0.1 ×136.286 g/mol

= 13.629 g
