Quantitative Chemistry - Coggle Diagram

- - - - Relative formula mass of reactants = relative formula mass of products
      - Mass of products = mass of reactants
    - - Equal number of atoms of each element on each side of the equation
    - - Mass increase implies gaseous reactant
      - Mass decrease implues gaseous product
      - Unsealed reaction container
  - - - Errors in measuring equipment
      - Random errors
  - - - Relative atomic mass is the larger number found on the periodic table (mass number)
- - - - Avagadro's constant: 6.03*10^23
  - - - Calculate moles of known reactant/ product
      - Determine ratio of known reactant/ product to unknown reactant/ product
      - Find mass of unknown reactant/ product
  - - - Amount of product formed is directly proportional to amount of limiting reactant
      - Calculate the mass of product formed using the mass of the limiting reactant and the balanced equation
        
        Calculate moles of limiting reactant
        
        Determine ratio of limiting reactant to product
        
        Find mass of product
- - - - (Relative formula mass of desired product/ Sum of relative formula masses of all reactants) *100
    - - Low atom economy produces waste products which need to be disposed of
        
        Landfill
    - - Waste products can be expensive to remove
      - Raw materials need to be bought more regularly for low economy processes
  - - - Product lost when separated from reaction mixture
      - Unexpected side reactions
      - Incomplete rreaction
        
        Reversible reaction
        
        E.g. Haber process
    - - (Mass of actual yield/ Mass of theoretical yield) *100
- - - - Where volume is in dm^3 and the mass of the gas is measured in grams
