What is meant by the chemical formula? Write some of the compounds you know with their chemical formula.

 The chemical formula is a concise way of representing a chemical compound using the symbols of the elements that make it up. The formula gives the relative number of atoms of each element in the compound.

Here are some examples of chemical compounds and their formulas:

  1. Water (H2O)
  2. Carbon dioxide (CO2)
  3. Methane (CH4)
  4. Ethanol (C2H5OH)
  5. Sodium chloride (NaCl)
  6. Glucose (C6H12O6)
  7. Calcium carbonate (CaCO3)
  8. Ammonia (NH3)
  9. Nitric acid (HNO3)
  10. Sulfuric acid (H2SO4)

How many elements of unsaturation does a molecule with the chemical formula C5H8 have?

  Unsaturation in a molecule refers to the presence of double or triple bonds between the carbon atoms or the presence of a ring structure. To determine the number of elements of unsaturation in a molecule, you can use the following formula: Number of elements of unsaturation = (2 x number of rings) + (2 x number of double bonds) + (3 x number of triple bonds) In the case of C5H8, the molecule has no double bonds, triple bonds, or ring structures, so the number of elements of unsaturation is 0.
