Okay, let's continue. (f) Position of M M is an element in the 3rd period and is an alkaline earth metal (Group 2). This element is Magnesium (Mg). Its position in the periodic table grid would be: Period 3, Group 2. 2. (a) Chromatography (i) On the diagram: (I) Label the baseline (origin) (II) Show the positions of all the spots after development The baseline* is the horizontal line at the bottom where spots A, B, C, and D are initially placed. After development: Spot A moves to 8 cm. Spot B moves to 3 cm. Spot C moves to 6 cm. Spot D separates into two spots, one at 6 cm and one at 8 cm. Here is the diagram with the labels and developed spots: |l| 8 cm X (A) X (D) \\ 7 cm \\ 6 cm X (C) X (D) \\ 5 cm \\ 4 cm \\ 3 cm X (B) \\ 2 cm \\ 1 cm \\ Baseline (Origin) X (A) X (B) X (C) X (D) \\ (Note: In a real diagram, you would draw the spots at the indicated heights above the baseline.) (ii) Identify the substances present in mixture D Mixture D separated into two spots that moved 6 cm and 8 cm. Substance A moved 8 cm. Substance C moved 6 cm. Therefore, mixture D contains substances A and C. 2. (b) Separation of ammonium chloride and anhydrous calcium chloride Step 1: Heat the solid mixture gently in an evaporating dish. Step 2: Ammonium chloride will sublime (change directly from solid to gas) and then deposit as a solid on a cooler surface (e.g., a watch glass placed over the dish). Step 3: Anhydrous calcium chloride will remain in the evaporating dish as it does not sublime. 2. (c) Miscible and immiscible liquids (The table for this question is not provided in the image.)
