The correct answer is Halite.

Key Points

• Halite is the mineral form of sodium chloride (NaCl), commonly known as rock salt.
• Halite forms through the evaporation of seawater and is typically found in sedimentary rock formations.
• It is an evaporite mineral, which means it crystallizes from evaporating brine.
• Commercially, halite is mined for use as table salt, road salt, and in various industrial processes.
• Halite crystals are typically cubic in structure and can range in color from clear to white, and sometimes even shades of pink or blue due to impurities.

 Additional Information

• Hematite
  • Hematite is an iron oxide mineral with the formula Fe₂O₃.
  • It is one of the most abundant minerals on Earth's surface and in the shallow crust.
  • Hematite is primarily used in the production of iron and steel.
  • The mineral can appear in colors such as black to steel or silver-gray, brown to reddish-brown, or red.
• Limonite
  • Limonite is a generic term for a mixture of hydrated iron oxide minerals.
  • It is often used as a low-grade iron ore and can be found in various geological environments.
  • Limonite is typically yellow-brown or ochre-colored.
• Siderite
  • Siderite is a carbonate mineral composed of iron(II) carbonate (FeCO₃).
  • It is a valuable iron mineral, used in the production of iron and steel.
  • Siderite is typically found in sedimentary deposits and can vary in color from yellow to brownish or gray.

The correct answer is Table salt.

Key Points

• Table salt, also known as sodium chloride, is a classic example of an ionic compound.
• Ionic compounds are formed by the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions.
• In the case of table salt, sodium (Na) loses one electron to become a positively charged sodium ion (Na+).
• Chlorine (Cl) gains this electron to become a negatively charged chloride ion (Cl-).
• The opposite charges of the ions create a strong electrostatic force of attraction, known as an ionic bond.
• Table salt is highly soluble in water and has a characteristic crystalline structure.
• Common uses of table salt include seasoning food and as a preservative.

 Additional Information

• Turmeric
  • Turmeric is a spice derived from the rhizome of the plant Curcuma longa.
  • It contains a compound called curcumin, which has anti-inflammatory and antioxidant properties.
  • Turmeric is commonly used in cooking, particularly in Indian cuisine, and in traditional medicine.
• Sugar
  • Sugar, specifically sucrose, is a disaccharide composed of glucose and fructose.
  • Sugar is a covalent compound, not an ionic compound.
  • It is widely used as a sweetener in food and beverages.
• Glucose
  • Glucose is a simple sugar and an important energy source in living organisms.
  • It is a monosaccharide with the molecular formula C6H12O6.
  • Glucose is also a covalent compound, not ionic.

The correct answer is Na ions are positively charged, and Cl ions are negatively charged.

Key Points

• NaCl, or common salt, consists of sodium (Na) ions and chloride (Cl) ions.
• In ionic compounds like NaCl, the sodium atom loses one electron to become a positively charged Na⁺ ion.
• The chlorine atom gains one electron to become a negatively charged Cl^- ion.
• The resulting electrostatic attraction between Na⁺ and Cl^- ions forms the ionic bond that holds the compound together.
• This process of electron transfer leads to the formation of a stable ionic structure.
• NaCl is a crystalline solid at room temperature.
• It is widely used in various industries and in daily life as table salt.

 Additional Information

•  Ionic compounds
  • Ionic compounds are typically formed between metals and non-metals.
  • They have high melting and boiling points due to the strong electrostatic forces between ions.
  • Ionic compounds are generally soluble in water and other polar solvents.
  • They conduct electricity when dissolved in water or molten.
