Zinc and magnesium metal each react with HCl according to the following equation: Zn + 2 HCl= ZnCl2 + H2 Mg + 2 HCl = MgCl2 + H2 A 10.00 g mixture of zinc and magnesium is reacted with just enough of HCl so that all the zinc and magnesium in the mixture have reacted and no excess HCl is added. The resulting solution requires 156 mL of 3.00 M silver nitrate to precipitate all the Cl- ions in the solution to form silver chloride. Calculate the percent by mass of magnesium in the original mixture. (2)

Question
- Zinc and magnesium metal each react with HCl according to the following equation:
Zn + 2 HCl= ZnCl2 + H2
Mg + 2 HCl = MgCl2 + H2
A 10.00 g mixture of zinc and magnesium is reacted with just enough of HCl so that all the zinc and magnesium in the mixture have reacted and no excess HCl is added. The resulting solution requires 156 mL of 3.00 M silver nitrate to precipitate all the Cl- ions in the solution to form silver chloride. Calculate the percent by mass of magnesium in the original mixture. (2)
