Answer the following questions:
You have learned that metals react with acids to produce salt and hydrogen gas, depending on their position in the reactivity series. You are given five metals \(Mg\), \(Al\), \(Zn\), \(Fe\), and \(Cu\) and asked to test their reactions with dilute hydrochloric acid (\(HCl\)) and dilute nitric acid (\(HNO_3\)).
i. Which metal will react most vigorously with dilute \(HCl\), producing heat and hydrogen gas?
ii. Which of the following metals reacts slowly with dilute \(HCl\) and produces a pale green solution?
