Answer 1

Properties of Table Salt (Sodium Chloride) and Sugar:

Table Salt (Sodium Chloride): - Chemical Formula: NaCl - Appearance: White crystalline solid - Taste: Salty - Solubility: Highly soluble in water - Melting Point: 801 degrees Celsius - Boiling Point: 1465 degrees Celsius - Conductivity: Conducts electricity when dissolved in water - Usage: Commonly used as a seasoning and preservative in food

Sugar: - Chemical Formula: C12H22O11 - Appearance: White crystalline solid (granulated sugar) or brown solid (brown sugar) - Taste: Sweet - Solubility: Soluble in water - Melting Point: 186 degrees Celsius (for granulated sugar) - Boiling Point: Decomposes before boiling - Conductivity: Does not conduct electricity when dissolved in water - Usage: Used as a sweetener in food and beverages

Properties of Acetic Acid (Vinegar) and Water:

Acetic Acid (Vinegar): - Chemical Formula: CH3COOH - Appearance: Colorless liquid with a pungent smell - Taste: Sour - Solubility: Highly soluble in water - Melting Point: 16.6 degrees Celsius - Boiling Point: 118.1 degrees Celsius - Conductivity: Conducts electricity when dissolved in water - Usage: Used as a condiment, preservative, and cleaning agent

Water: - Chemical Formula: H2O - Appearance: Colorless liquid - Taste: Tasteless - Solubility: Highly soluble in many substances - Melting Point: 0 degrees Celsius - Boiling Point: 100 degrees Celsius - Conductivity: Can conduct electricity when ions are present (e.g., when dissolved salts are present) - Usage: Essential for life, used in various industrial processes, and as a solvent

Please note that the properties mentioned above are general characteristics and may vary depending on the specific type or purity of the substances.
