  • Gas Volumes
    • 3 ways to collect gas
      • Burette- filled with water, read from scale
      • Measuring cylinder
      • Gas syringe
    • 1 mole of gas takes up 24dm3
      • 3 moles= 3x24=72
        • The number of moles can be found if the volume is known
    • When magnesium reacts with acid, the amount of hydrogen is proportional to the limiting reactant
      • Limiting reactant= reactant not in excess
        • Used up first
      • No more particles to collide
    • Steeper the gradient of a graph, the more gas is produced
