Question

(c)

(C) You have a piece of magnesium of unknown mass, and a beaker of water in which is dissolved as unknown amount of hydrogen chloride. Design an experiment to determine which reactant is the limiting reactant. In your answer, include any physical changes that you might observe.

Answer 1

C) you have a piece of Mg of unknown mors, and a be plece of Mg of unknown moss, and a beaker of water in which lo dissowed as unknown amount of Hal. Design an experiment to determine which reactant is the limiting reactant In your answer & include any physical changes that you might Observe. Ans- * This reaction is a good example of a single replacement reaction can oxidation -- reduction reaction). * Mg metal is an active metal, it can easily react with HUL Mg (s) + 2 HCl Lag) mala cag) + Hacg) salt gars * When Mg reacts with Ha, hydrogen gors and solieble Maula are produced. * Mg is onidized, losing two electrons, hydrogen po reduced from Htion to Ha gas when the electron score transferred to it. The net fonic equation for this reaction is : Mg cs) + au caq) → Moringa + Macg) ound controllable as P4 PS not * The reaction in moderate exothermic and explosive
