List of General Chemistry Laws

2677

When you’re studying Chemistry, these are the laws that you have to take note.

Conservation of Energy
Conservation of Energy
  1. Avogadro’s Law – Ideal gases under equal temperature and pressure conditions will also contain equal number of particles, whether it is molecules, atoms, electrons, etc.
  2. Boyle’s Law – The confined gases’ volume is inversely proportional to the pressure at constant temperature.
  3. Charles’ Law – The confined gas volume is directly proportional to the absolute temperature at constant pressure.
  4. Conservation of Energy – Being the First Law of Thermodynamics, it states that energy can be neither created nor destroyed, therefore making the universal energy constant.
  5. Conservation of Mass – Matter can be neither created nor destroyed, though it can undergo chemical changes while the mass, however, remains the same.
  6. Dalton’s Law – The gases mixture’s pressure is equal to the sum of component gases’ partial pressures.
  7. Definite Composition – Two or more elements of a definite weight chemically combined are needed to form a compound.
  8. Dulong and Petit’s Law – In most metals, 6.2 calories are needed to raise the temperature of 1g by 1 degree centigrade.
  9. Faraday’s Law – The weight of any element during electrolysis is proportional to the electricity’s quantity and to the element’s weight.
  10. Gay-Lussac’s Law – The ratio between the gas volumes and product combined can be expressed in whole numbers.
  11. Graham’s Law – The diffusion or effusion rate of a gas is inversely proportional to its molecular mass’ square root.
  12. Henry’s Law – The gas’ solubility is directly proportional to the applied pressure, unless it’s highly soluble.
  13. Ideal Gas Law – The ideal gas’ state is determined by volume, pressure and temperature.
  14. Multiple Proportions – The mass of one element combined with a fixed mass of another, is done in a small whole number-ratio system.
  15. Periodic Law – Every element’s chemical property varies according to their atomic number.
  16. Second Law of Thermodynamics – Heat cannot flow on its own from cold to a hot area.
