  1. Common Compounds

  2. Water Formula: H2O Where is it found? Liquid water covers most of the Earth’s surface. Frozen water (ice) can be found near the poles. Water vapor is found in the atmosphere. Uses: Water is essential to all life, and is a major force in the shaping of the Earth’s surface.

  3. Carbon dioxide Formula: CO2 Where is it found? CO2 exists as a gas in the atmosphere. It is produced by fires, volcanoes, fossil fuel use, and respiration (breathing) Uses: CO2 is used by plants during photosynthesis. It is a major “greenhouse gas” that impacts global climate. Frozen CO2 is known as “dry ice”

  4. Sodium chloride Formula:NaCl Where is it found? NaCl (salt) is found in the oceans and in underground deposits left by ancient oceans. Uses: Salt is used in cooking, seasoning, and preserving food. It is also required for the health of many living things.

  5. Glucose (Sugar) Formula: C6H12O6 Where is it found? Sugar is produced by plants during photosynthesis. Uses: Sugar is used as an energy source by many organisms. It is in many foods. It has a sweet taste.

  6. Calcium carbonate Formula: CaCO3 Where is it found? Occurs naturally in limestone, marble, and chalk. It is a major part of marine animal shells, pearls, and eggshells. Uses: CaCO3 is used in many industries, pottery, and as a calcium supplement.

  7. Silicon dioxide (Silica) Formula: SiO2 Where is it found? It is the most common mineral on the Earth’s surface. It is a major part of sand and quartz. Uses: SiO2 is used to make glass, fiber optics, and many industrial applications.
