Chemistry: 3a
- Hardness of water
  - Hard water
    - contains dissolved calcium and magnesium compounds
      - rain water comes into contact with rocks and compounds dissolve in the water
  - soft water
    - produces lather easily
      - less soap needed
    - heating systems last longer in appliances(saves money)
  - titration experiment can be done to compare hardness of water
- Reversible Reactions
  - if a reversible reaction takes place in a closed system equilibrium is reached
    - equilibrium is when both sides of reaction occur at same rate
  - increasing temp favours the endothermic reaction and decreases the rate of the exothermic
  - increasing pressure in a gaseous reaction favours the reaction with less molecules
