Okay, BISMARK. Let's tackle question 1. Step 1: Identify metals and non-metals. Based on general properties, samples A (nail/iron) and B (copper) are metals. Samples C (sulphur) and D (carbon/charcoal) are non-metals. Step 2: State properties for Sample A (Iron). Iron (A) is identified as a metal due to the following properties: • Appearance: Silvery-grey and lustrous. • Malleability/Ductility: It is malleable (can be hammered into sheets) and ductile (can be drawn into wires). • Conductivity: It is a good conductor of electricity. • Solubility: It is insoluble in water. Step 3: State properties for Sample B (Copper). Copper (B) is identified as a metal due to the following properties: • Appearance: Reddish-brown and lustrous. • Malleability/Ductility: It is malleable and ductile. • Conductivity: It is a good conductor of electricity. • Solubility: It is insoluble in water. Step 4: State properties for Sample C (Sulphur). Sulphur (C) is identified as a non-metal due to the following properties: • Appearance: Yellow and dull. • Malleability/Ductility: It is brittle (breaks easily, not malleable or ductile). • Conductivity: It is a poor conductor of electricity. • Solubility: It is insoluble in water. Step 5: State properties for Sample D (Carbon/Charcoal). Carbon (D) is identified as a non-metal due to the following properties: • Appearance: Black and dull. • Malleability/Ductility: It is brittle. • Conductivity: It is a poor conductor of electricity. • Solubility: It is insoluble in water.
