Zirconium chloride reacts with magnesium to produce Zirconium. The process iscalled Knoll process.ZrCI4 + 2Mg → Zr + 2MgCI2How many moles Zr would be produced if 0.2 mol of Mg metal is used in thereaction?

Correct answer: A. 0.1

  • A. 0.1
  • B. 0.01
  • C. 0.20
  • D. 0.05

Explanation

The balanced chemical equation for the reaction is:ZrCl4 + 2Mg → Zr+ 2MgCl2According to the balanced equation, 1 mole of Zirconium (Zr) is produced for every 2 moles of magnesium (Mg) used in the reaction.Given that 0.2 mol of Mg is used, the moles of Zr produced can be calculated:Moles of Zr = Moles of Mg / 2Moles of Zr = 0.2 / 2 = 0.1

About Fundamental Concepts of Chemistry

Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
