Igcse Model Questions Vol1 2021 Chemistry Question 17
Practice objective / multiple choice question 17 from the 2021 Igcse Model Questions Vol1 Chemistry examination.
A metal strip of unknown identity loses exactly \(1.5\ \text{g}\) after reacting completely with excess aqueous silver nitrate solution, forming a precipitate of \(5.00\ \text{g}\) of metallic silver. The reaction is \( \text{X} + 2\text{AgNO}_3 \rightarrow \text{X(NO}_3)_2 + 2\text{Ag} \). Given the atomic masses: Zn = \(65.38\ \text{g\ mol}^{-1}\), Fe = \(55.85\ \text{g\ mol}^{-1}\), Mg = \(24.31\ \text{g\ mol}^{-1}\), determine which metal X is and calculate the mass of X that reacted.
