- 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
- 3 moles= 3x24=72
- 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
- Limiting reactant= reactant not in excess
- Steeper the gradient of a graph, the more gas is produced
